Vietnam (VN)
Vietnam is a dynamic, rapidly developing Socialist Republic stretching 1,650km down the eastern coast of the Indochinese Peninsula — a country of extraordinary geographical diversity, from the karst mountains of the north and the Red River Delta, through the stunning coastline of the Central region, to the vast Mekong Delta in the south.
⚠️ Costly Mistakes to Avoid
The most expensive and common mistakes expats make in Vietnam — and exactly how to avoid them.
Drug Laws: Death Penalty for Trafficking
Vietnam imposes the death penalty for drug trafficking offences involving 100g or more of heroin or methamphetamine, or 30kg or more of opium. Possession of even small quantities for personal use carries imprisonment of 1–5 years. There are no exceptions for tourists or foreigners.
⚡ Death penalty for trafficking; lengthy imprisonment (up to 20 years) for possession. No diplomatic immunity for foreign nationals.
✅ Never carry, purchase, transport or consume illegal drugs in Vietnam. Do not accept packages from strangers. Be aware that some nightlife venues in HCMC and Hanoi may involve drug offers — decline and leave.
Visa Overstay: Immediate Consequences
Overstaying your visa — even by one day — triggers fines, a formal entry ban, and forced departure. The immigration authority (Immigration Department — Cục Quản lý xuất nhập cảnh) tracks all entries and exits electronically. Overstays are flagged immediately at the border.
⚡ Fine of VND 3,000,000–5,000,000 per day of overstay; possible 1–5 year entry ban; forced deportation at your own cost; potential difficulties obtaining future Vietnamese visas.
✅ Monitor your visa expiry date carefully. E-Visas are exactly 90 days from entry — set a calendar reminder 2 weeks before expiry. Apply for an extension or change of visa status before expiry, not on the day it expires. Never rely on a border crossing to "reset" your visa status — visa exemption periods are set on entry, not exit.
Working Without a Valid Work Permit
All foreigners working in Vietnam (employed, contracted or self-employed providing services) must hold a valid work permit (Giấy phép lao động) or a confirmed work permit exemption. Working on a tourist visa, e-visa or any non-work visa is illegal regardless of how payment is received (including working remotely for an overseas employer on Vietnamese soil if the employer has a Vietnamese entity).
⚡ Deportation, fine of VND 75,000,000–100,000,000 (employer); fine of VND 15,000,000–25,000,000 (employee); employer may face suspension of business licence.
✅ Ensure your employer has applied for and obtained your work permit before you begin work. Request a copy of the work permit for your records. If exempt, obtain a written work permit exemption certificate from DOLISA. Remote workers: consult a Vietnamese employment lawyer about your specific circumstances.
Property Fraud and Sổ Hồng (Red Book) Scams
Property fraud is a significant risk in Vietnam. Common schemes include: selling the same property to multiple buyers, forged Sổ Hồng (Land Use Rights Certificates), selling properties in planning restriction zones, and developers selling units in projects without a construction permit. Under Housing Law No. 27/2023/QH15, foreigners can own apartment units (max 30% of units per building) but CANNOT own land.
⚡ Financial loss of entire purchase price; no legal recourse if Sổ Hồng is forged; inability to sell or transfer the property; potential eviction with no compensation if purchase is void.
✅ Always verify the original Sổ Hồng at the provincial Department of Natural Resources and Environment (Sở TNMT). Use a licensed Vietnamese real estate lawyer (not the developer's lawyer). Check for planning restrictions via the local People's Committee. Never pay the full purchase price before the Sổ Hồng transfer is registered in your name. For new developments: verify construction permit and project legal status before signing.
Motorcycle and Traffic Accident Risk
Vietnam has one of the highest road traffic fatality rates in Southeast Asia. Over 7,000 people die annually in road accidents. The risk is highest on motorcycles — the dominant form of transport. Traffic ignores lane markings, runs red lights frequently, and flows in unexpected directions at junctions. Pedestrian crossings are not reliably respected.
⚡ Vietnam's road accident fatality rate per 100,000 vehicles is among the highest in ASEAN. Motorcycle accidents are the leading cause of expat hospitalisation and medical evacuation.
✅ Always wear a full-face helmet (not a half-shell). Never drink and ride — zero alcohol limit since 2020 (Decree 100/2019). If hiring a motorbike: ensure international driving licence covers motorcycle category and you have Vietnamese motorbike licence (Category A1/A2). Use Grab (rideshare) or taxi for unfamiliar routes. Cross streets slowly and predictably — maintain eye contact with drivers, move at a constant pace.
Typhoons and Flash Flooding (Central and Northern Vietnam)
Vietnam is struck by an average of 6–10 tropical storms and typhoons per year, primarily affecting Da Nang, Hue, Hội An and coastal central provinces (July–November). HCMC and the Mekong Delta experience severe urban flooding during monsoon season (May–November). Flash floods in northern mountainous areas (Sapa, Ha Giang) can be sudden and lethal.
⚡ Death or injury from flooding, storm surge or landslide; property damage; disruption of all transport (flights, roads, rail); potential evacuation requirements.
✅ Monitor the National Centre for Hydro-Meteorological Forecasting (nchmf.gov.vn) and weather apps during typhoon season. Register with your country's embassy for emergency alerts. If a typhoon is approaching coastal areas: move inland immediately — do not shelter in place in a ground floor room. For monsoon flooding in HCMC: avoid underpass roads that flood rapidly; keep emergency bag ready. Ensure rental property is above known flood levels before signing lease.
Gem, Jewellery and Silk Scam (Tourist Areas)
A widespread scam in Hanoi Old Quarter, Hội An and tourist markets where victims are convinced to purchase gems, jewellery or silk items at "wholesale" or "factory" prices, promised they can resell at huge profit in their home country. Items are worthless imitations. Typically involves a friendly local guide or taxi driver who takes a commission for bringing victims to the shop.
⚡ Financial loss of USD 100–10,000+. No refund available. Items are unsaleable. Vietnamese police rarely act on tourist scam complaints.
✅ Never buy gems, jewellery or silk for investment purposes in Vietnam based on a stranger's recommendation. Do not accept transport from strangers who offer to show you a "special shop." Any mention of being able to resell items for profit in your home country is a guaranteed scam signal.
Tet Holiday: Complete Business Closure (January/February)
Tet Nguyên Đán (Lunar New Year) is Vietnam's most important holiday. In 2026, Tet falls on January 29 (Lunar New Year's Eve). The official holiday period is January 27–February 3, 2026. During Tet: nearly all government offices, banks, local businesses, clinics, pharmacies and courts close entirely. Many close from 1–2 weeks before Tet and do not fully reopen until February 10–15.
⚡ Inability to process visas, work permits, notarisations, tax filings, or banking transactions for 2–3 weeks. Medical care limited to major international hospitals. Domestic flights fully booked months in advance. Businesses effectively shut down.
✅ Plan all administrative tasks (visa renewals, work permit applications, notarisations, contract signings) at least 6 weeks before Tet. Stock essential medications. Book Tet period travel by November of the prior year. International hospitals (FV, Vinmec, Hanoi French Hospital) remain open throughout Tet.
Currency Confusion and Zero-Counting Errors
Vietnamese Dong (VND) is quoted in millions for most significant transactions. USD 1 ≈ VND 25,000. A single zero-counting error when paying in cash can mean overpaying by 10× or underpaying and causing offense. Counterfeit VND 500,000 notes exist — always check notes received.
⚡ Overpayment by an order of magnitude; accepting counterfeit notes (no recourse); difficulties at markets and informal businesses that do not accept card payment.
✅ Always count zeros carefully before paying. VND 500,000 (five hundred thousand, NOT five million). VND 1,000,000 = approximately USD 40. Use the currency converter on your phone until the denominations become instinctive. Never exchange money at unauthorised street vendors — use ATMs, official exchange counters, or licensed gold shops (tiem vang). Verify large denomination notes under UV light.
Political Expression and Social Media
Vietnam operates under a one-party system (Communist Party of Vietnam). Criticising the government, the party, or party leaders — in person or on social media — is illegal under Article 331 of the Penal Code (spreading anti-state information) and the Cybersecurity Law 2018. Foreign nationals are not exempt.
⚡ Arrest, imprisonment (5–12 years under Article 331), deportation, or revocation of visa/work permit. Social media posts made while in Vietnam — even shared privately — can be monitored.
✅ Avoid all public commentary on Vietnamese politics, the party, or government leaders — in speech, writing, or social media. Do not share, like or amplify political content about Vietnam from within Vietnam. Use a VPN if accessing news services that may be blocked (although VPN use itself exists in a legal grey area under the Cybersecurity Law).
Severe Traffic Fines Under Decree 168/2024
Decree 168/2024/ND-CP (effective January 2025) introduced dramatically increased traffic fines in Vietnam. Running a red light: VND 4,000,000–6,000,000 (car), VND 800,000–1,000,000 (motorbike). Driving the wrong way: VND 10,000,000–12,000,000 (car). DUI: up to VND 40,000,000 + 24-month licence suspension. Mobile phone while driving: VND 800,000–1,000,000 (motorbike), VND 2,000,000–3,000,000 (car).
⚡ Large fines enforced strictly since January 2025. Traffic cameras are being rolled out across HCMC and Hanoi. Fines must be paid to reclaim vehicle at impound.
✅ Observe all traffic signals and lane markings. Never use a mobile phone while riding or driving. Never drink and drive (zero tolerance). Carry valid licence (Vietnamese or IDP) at all times. Know the fine schedule for common infringements.
Fake Taxis and Rideshare Overcharging
Fake taxis (often using modified meters that run fast, or similar branding to legitimate companies) operate near airports, bus stations and tourist areas. At Nội Bài Airport (Hanoi) and Tân Sơn Nhất Airport (HCMC), unlicensed taxi drivers aggressively approach arriving passengers.
⚡ Overcharging by 3–10× the legitimate fare. In some cases, passengers have been driven to an unknown location and charged extremely inflated amounts before being allowed to leave.
✅ Use Grab (most reliable option — fare shown in advance, driver tracked). For taxis: use only Mai Linh (green, 028 3838 3838) or Vinasun (white, 028 3827 2727) — verify logo and meter before entering. At airports: book via official airport taxi desk or Grab only. Never accept rides from strangers approaching in the arrivals hall.
Banking Limitations for Foreign Residents
Foreign residents face restrictions in Vietnamese banking: savings account interest rates for foreigners are regulated (0% on foreign currency accounts since 2016); some banks require a TRC (temporary residence card) to open an account (a work permit may suffice); credit cards and overdraft facilities are rarely issued to new foreign residents without a long credit history in Vietnam. International transfers face daily limits and may require declaration at customs for cash amounts exceeding USD 5,000.
⚡ Inability to save in USD at interest; difficulty accessing credit; friction with large international transfers; possible delays in receiving overseas income.
✅ Open a VND account at Vietcombank or HSBC Vietnam early — bring passport, TRC, work permit, and tax code. For international transfers: use Wise (licensed in Vietnam) for best rates. Declare cash over USD 5,000 or equivalent at customs on arrival. Keep VND 20,000,000–50,000,000 cash emergency fund — ATMs occasionally run out around Tet.
Landlord Utility Markups Above Legal Limits
Vietnamese law allows landlords to charge tenants for electricity at the EVN (state utility) rate — approximately VND 2,000–3,500 per kWh depending on consumption tier. However, many landlords — particularly in serviced apartments and shared houses — charge VND 4,000–6,000/kWh or issue lump-sum charges without showing meter readings. Water markups are also common.
⚡ Overpayment of VND 500,000–3,000,000/month on utilities. Disputes with landlord that are difficult to resolve without bilingual legal support.
✅ Before signing a lease: ask to see the EVN bill for the previous month. Specify in the lease that electricity is charged at the EVN rate (and include the current kWh price). Take and photograph electricity/water meter readings on move-in day. Request itemised utility bills each month.
Counterfeit Goods and Intellectual Property Risk
Counterfeit goods — electronics, clothing, handbags, watches, cosmetics, pharmaceuticals — are widely available in Vietnamese markets (Bến Thành, Đồng Xuân, Saigon Square) and some online platforms. Purchasing for personal use has low enforcement risk inside Vietnam, but carrying counterfeit branded goods through your home country customs on departure may result in confiscation and fines.
⚡ Confiscation of counterfeit goods at border on return home; potential customs fines; safety risk from counterfeit electronics (fire risk) and counterfeit pharmaceuticals.
✅ Buy medications only from reputable pharmacy chains (Long Châu, Pharmacity, An Khang). Check that electronics carry proper CE/FCC marks. Do not carry counterfeit branded goods through airport customs — check your home country's import regulations on counterfeit goods.
Language Barriers in Emergency and Public Healthcare
In public hospitals and provincial healthcare settings, English proficiency among staff — including emergency room doctors — may be limited or absent. In a medical emergency, this can critically delay diagnosis and treatment. Even in HCMC and Hanoi, many public hospital staff speak Vietnamese only.
⚡ Delayed or incorrect diagnosis; inability to communicate symptoms or medical history; potential for medication errors due to miscommunication.
✅ Carry a medical information card translated into Vietnamese (blood type, allergies, chronic conditions, current medications). Register with an international clinic (Family Medical Practice, Pacific Cross) before any emergency occurs. Keep the FV Hospital emergency number (+84 28 5411 3333) and your international insurer's 24/7 hotline saved in your phone. For non-emergency care: always use an international private hospital where English-speaking staff are guaranteed.
Air Pollution: Severe in Hanoi (October–March)
Hanoi regularly records AQI (Air Quality Index) levels in the Unhealthy (151–200) and Very Unhealthy (201–300) range during October to March — caused by traffic emissions, industrial pollution, and seasonal atmospheric inversions. HCMC has lower but still concerning pollution levels year-round. PM2.5 concentrations in Hanoi frequently exceed WHO guidelines by 10–20×.
⚡ Respiratory illness, aggravation of asthma, cardiovascular strain; increased hospital visits. Children and elderly are most vulnerable. Long-term exposure linked to chronic respiratory disease.
✅ Monitor air quality daily via Air Visual app (IQAir) or Zalo weather alerts. On high AQI days (>150): wear an N95 or KN95 mask outdoors, keep windows closed, use air purifier indoors. Consider a quality air purifier (Xiaomi, Sharp, Philips) for bedroom and living room. Families with young children: consider location of apartment relative to main roads.
Food Safety and Water Quality
Tap water in Vietnam is NOT safe to drink without treatment — it may contain bacteria, heavy metals (particularly in older pipe systems), and elevated chlorine. Ice at street food stalls may be made from unfiltered water. Raw vegetables at street food can carry contamination from irrigation water practices.
⚡ Gastrointestinal illness (traveller's diarrhoea), typhoid (if not vaccinated), hepatitis A (if not vaccinated), foodborne parasites (Anisakis, liver flukes from freshwater fish dishes).
✅ Drink only bottled water, filtered water (reverse osmosis) or boiled water. At restaurants: ask for ice from machines (đá viên) rather than block ice. Eat at busy restaurants with high turnover. Ensure vaccinations for typhoid and hepatitis A are current before arrival. Carry ORS (Oral Rehydration Salts — Oresol/Hydrite) for dehydration management.
Internet Censorship and VPN Use
Vietnam blocks numerous websites including Facebook (periodically), Google services (intermittently), foreign news sites, and VPN services under the Cybersecurity Law 2018. Many popular VPNs are blocked at the ISP level, though technical workarounds exist. The law technically requires VPN providers to store user data locally.
⚡ Restricted access to work tools, banking platforms, and social media. Using a VPN is in a legal grey area — enforcement against individuals is rare but legally possible. Businesses using VPNs for legitimate remote work purposes are generally tolerated.
✅ Install a reputable VPN (ExpressVPN, NordVPN, Mullvad) before arriving in Vietnam. Keep an alternative VPN as backup. Use mobile data (4G) as an alternative when hotel/office WiFi blocks VPN. For business use: consult a Vietnamese IT/legal adviser on compliant options.
Rental Deposit: No Escrow Protection
Vietnam has no statutory tenancy deposit protection scheme. Deposits of 1–3 months' rent are paid directly to the landlord with no escrow or third-party protection. Deposit disputes are among the most common expat complaints — landlords may withhold deposits citing minor damage, unpaid utilities, or unilateral deductions.
⚡ Deposit loss of VND 10,000,000–50,000,000+ with limited legal recourse. Court proceedings for deposit disputes are slow (6–18 months), expensive relative to the deposit amount, and outcomes uncertain.
✅ Document the apartment condition in writing and video before moving in — have landlord sign the handover checklist. Specify in the lease that normal wear and tear is not deductible from the deposit. Specify the exact conditions and timeline (5–7 days) for deposit return after vacating. For high-value rentals: consider using a licensed real estate agent who manages the relationship and can mediate.
Banking Phishing and Online Fraud
Vietnam has a high rate of SMS and Zalo-based banking phishing attacks targeting both Vietnamese and foreign residents. Scammers impersonate Vietcombank, VPBank, or Techcombank via SMS with fake one-time password (OTP) requests, fake prize notifications, or fake account suspension alerts. Facebook Marketplace scams (advance payment then non-delivery) are also common.
⚡ Unauthorised bank transfers; loss of savings. Vietnamese banks have limited liability for phishing-related fraud if the customer revealed OTP codes.
✅ Never provide OTP codes to anyone — banks never ask for OTP by phone or SMS. Set up transaction alerts on your banking app for any transfer above VND 100,000. Use transaction confirmation biometrics (fingerprint/face) rather than SMS OTP where available. For online purchases: use MoMo or ZaloPay with buyer protection rather than direct bank transfer.
International Health Insurance: Direct Billing Gaps
Not all international health insurers have direct billing agreements with all international hospitals in Vietnam. Without pre-arranged direct billing, patients must pay upfront (often VND 5,000,000–50,000,000+) and then claim reimbursement. Some insurers exclude pre-existing conditions, mental health treatment, or dental care by default.
⚡ Large upfront medical costs; delayed reimbursement (30–90 days); potential uncovered expenses for excluded conditions.
✅ Before selecting health insurance: confirm it covers the specific hospitals you intend to use (Vinmec, FV, Family Medical Practice). Check the direct billing list on the hospital's website. Call your insurer before any planned hospitalisation to get pre-authorisation. Carry your insurance card and insurer emergency number at all times.
Cyclo, Xe Ôm and Tourist Transport Overcharging
Traditional cyclo (pedicab) rides, xe ôm (motorbike taxi) drivers, and souvenir vendors in tourist areas frequently quote prices 5–20× the local rate to foreign visitors. Prices are rarely displayed — quotes are given verbally and passengers agree without knowing the local rate.
⚡ Overpayment of VND 100,000–500,000 per incident; potential confrontation if you try to renegotiate after completing the journey.
✅ Always agree on the price before the journey begins and confirm clearly. Better: use Grab (fixed price shown upfront, no negotiation). For souvenir shopping: start negotiations at 20–30% of the first quoted price. Avoid cyclos in the Old Quarter entirely unless you enjoy the experience and don't mind paying a significant tourist premium.
Lottery Ticket Hawking and Begging Manipulation
Sellers — often elderly women or children — approach foreigners in tourist areas aggressively selling lottery tickets (vé số). While lottery tickets are legal in Vietnam, tourist-focused sellers use high-pressure guilt-based tactics. Separate from this, organised begging networks targeting foreigners operate in tourist areas, sometimes using children.
⚡ Financial solicitation; in rare cases, lottery ticket sellers have pickpocketed distracted tourists during the transaction.
✅ Politely decline with "Không, cảm ơn" (No, thank you). Avoid being distracted in crowded markets. If you wish to support charitable causes: donate directly to registered Vietnamese charities (Blue Dragon Children's Foundation, KOTO) rather than street giving.
Get a Vietnamese SIM Card Within 24 Hours of Arrival
A Vietnamese SIM card (Viettel, Mobifone, or Vietnamobile) is essential for: Grab registration, Zalo registration, banking OTP codes, and MoMo/ZaloPay payments. SIM cards require a passport for registration since 2023 — anonymous SIM purchase is no longer possible. Viettel has the best nationwide coverage.
⚡ Without a local SIM: unable to register for Grab, Zalo, banking apps, or receive OTP codes for financial transactions.
✅ Purchase a Viettel or Mobifone SIM at the airport (SIM kiosks in arrivals hall — e.g., Viettel at SGN and HAN airports) or at any telecom store. Bring your passport. A basic Viettel prepaid SIM with data costs approximately VND 100,000–200,000.
TM30 Foreigner Registration: Landlord Obligation
Under Vietnamese immigration law (Circular 55/2020), landlords (Vietnamese citizens or organisations) who accommodate foreign nationals must report this to the local police ward (công an phường) within 24 hours of the foreigner arriving, using form TM30. This is the landlord's legal obligation, but failure to complete TM30 can cause problems for the foreign resident when renewing visas or applying for a TRC.
⚡ Without TM30 registration, visa renewals and TRC applications may be rejected or delayed. Some immigration offices require proof of TM30 registration.
✅ Ask your landlord to complete TM30 registration with the local ward police within 24 hours of moving in. Confirm they have done so by asking for a copy of the receipt. If staying in a hotel or serviced apartment: this is done automatically by the property.
Motorbike Licence: Category A1 Required for 50–175cc
To legally ride a motorbike in Vietnam: you need a Vietnamese Category A1 licence (50–175cc, the range covering most Vietnamese commuter bikes and scooters) or Category A2 (>175cc). An International Driving Permit (IDP) does NOT cover motorcycles in Vietnam unless your home licence includes motorcycle category AND Vietnam has a bilateral licence exchange agreement with your country.
⚡ Under Decree 168/2024: riding without a valid licence: fine VND 800,000–2,000,000 + potential vehicle impoundment. International travel insurance may be void if riding without a valid licence.
✅ If you plan to ride: obtain a Vietnamese Category A1 licence via the driving test at the Provincial Department of Transport. This requires a theory test (available in English at some centres) and practical test. Alternatively: use Grab for motorbike transport and avoid riding yourself.
Personal Tax Code: Register Within 10 Days of Employment
All employees in Vietnam must register for a Personal Income Tax (PIT) code (mã số thuế cá nhân) with the General Department of Taxation (GDT). In practice, employers register on behalf of employees via the GDT's electronic portal. Your tax code is a 10-digit number that is used for all PIT filings, BHXH contributions, and financial reporting.
⚡ Without a tax code: employer cannot file correct PIT returns; penalties apply for late registration (VND 1,000,000–5,000,000). You cannot file for PIT finalisation or claim tax refunds without a tax code.
✅ Confirm with your employer's HR or accounting team that your tax code has been registered within the first month of employment. Check your code at the GDT portal (https://thuedientu.gdt.gov.vn) using your passport number.
Apostille and Document Authentication Requirements
Vietnam acceded to the Hague Apostille Convention on 29 August 2011. Most foreign documents presented to Vietnamese authorities (academic certificates, criminal background checks, birth certificates, marriage certificates) require an apostille from the issuing country's competent authority AND a certified Vietnamese translation from a licensed translation firm in Vietnam.
⚡ Rejected work permit applications, visa applications, or business registrations if documents lack apostille and certified translation. Additional delays of 4–12 weeks for document authentication.
✅ Obtain apostilles before coming to Vietnam (from the Foreign Commonwealth Office UK, State Secretary of State USA, Beglaubigung Germany, etc.). Have all documents professionally translated and notarised by a licensed Vietnamese translation firm. Allow 4–8 weeks for the full authentication process.
International Schools: Apply Early — Waiting Lists Are Long
Top international schools in HCMC (BIS HCMC, ISHCMC, SSIS) and Hanoi (UNIS Hanoi, BIS Hanoi, BVIS) have competitive waiting lists, particularly for primary years (Years 1–6). Annual fees are USD 15,000–28,000 and rising. Some schools prioritise families already enrolled or on embassy staff lists. Apply 12–18 months in advance for guaranteed September enrolment.
⚡ Children unable to access their preferred international school on arrival if application is left too late. Some families accept unsuitable schools or home-schooling temporarily.
✅ If you know you are relocating to Vietnam: contact BIS, ISHCMC, SSIS, UNIS or BVIS admissions 12+ months in advance. Request an information session and submit the registration form early. Ask your employer's HR whether they have school placement support or a corporate agreement with specific schools (common at large multinationals).
Motorbike Theft: Lock Always, Park Correctly
Motorbike theft is common in major Vietnamese cities. Thieves work quickly — an unlocked or poorly locked motorbike can disappear in under 60 seconds. Snatch-and-grab from moving motorbikes also targets phone and bag carriers (particularly in HCMC's District 1 and tourist areas).
⚡ Theft of motorbike (value VND 15,000,000–80,000,000); phone or bag snatching from moving vehicle. Motorbike theft claim requires police report (biên bản công an) and proof of ownership.
✅ Always use the steering lock AND a heavy-duty disc brake lock. Park in official guarded parking (bãi xe). On the street: carry bags on the shoulder away from traffic, hold phone against your chest (not outward). Do not hang bags on handlebars of parked motorbikes. Register your motorbike's chassis number and engine number.
Dengue fever is endemic throughout Vietnam year-round — daytime mosquito bites, no specific antiviral, avoid ibuprofen
Vietnam has endemic dengue fever driven by Aedes aegypti and Aedes albopictus mosquitoes. Unlike malaria mosquitoes that bite at night, Aedes mosquitoes are primarily daytime biters — most active 2 hours after sunrise and 2 hours before sunset. Transmission is year-round in southern Vietnam (Ho Chi Minh City, Mekong Delta, coastal provinces) with a pronounced peak during the rainy season (May–November). Northern Vietnam (Hanoi, Hải Phòng) sees lower but still significant transmission, peaking August–October. Major outbreaks have occurred in 2022–2024 across both regions with record case numbers in HCMC in 2022. There are four dengue serotypes (DENV 1–4) circulating simultaneously in Vietnam — prior infection with one serotype increases the risk of severe dengue haemorrhagic fever if infected with a different serotype. There is no approved antiviral treatment. Paracetamol only for fever management — ibuprofen and aspirin are contraindicated as they significantly increase bleeding risk. Warning signs of severe dengue requiring immediate hospital admission: severe abdominal pain, persistent vomiting, bleeding gums or nose, blood in urine or stool, sudden drop in temperature with dizziness (dengue shock syndrome).
⚡ Dengue causes severe incapacitation (high fever, intense joint and muscle pain — nicknamed "breakbone fever") for 7–14 days. Severe dengue haemorrhagic fever requires ICU-level care and can be fatal. Major international hospitals in HCMC (FV Hospital, Victoria Healthcare, Vinmec) and Hanoi (Vinmec Times City, Family Medical Practice) reliably diagnose and manage dengue.
✅ Apply DEET repellent (30%+ concentration) to all exposed skin every morning before leaving home — the daytime biting pattern means morning application is critical. Use permethrin spray on clothing and shoes. Keep window and door screens in good repair — repair holes immediately. Eliminate standing water at home weekly: empty plant saucers, flower vases, buckets, and check air conditioner condensation trays. In high-risk periods (rainy season), use plug-in mosquito repellents in bedrooms. If you develop fever: see a doctor promptly and ask for an NS1 antigen rapid test (detectable days 1–5) or a dengue PCR test. Avoid ibuprofen and aspirin entirely until dengue is ruled out. The NS1 test is available at all major clinics and hospitals in Vietnam for approximately VND 150,000–300,000.
Zalo: The Essential App for Daily Life in Vietnam
Zalo is Vietnam's dominant messaging and payments platform with 74 million users — equivalent to WhatsApp in the West. Landlords, employers, clinics, and government services communicate primarily via Zalo. Many businesses only respond to Zalo messages, not email. Zalo also integrates with ZaloPay for bill payments and QR code transfers.
⚡ Expats without Zalo are effectively cut off from the primary communication channel used by Vietnamese contacts, service providers and community groups.
✅ Download Zalo immediately on arrival (available on iOS and Android — search "Zalo" in App Store/Google Play). Register with your Vietnamese phone number (SIM card required). Join relevant expat Zalo groups for your city.
Grab: The Only Reliable Transport App in Vietnam
Grab (not Uber — Uber exited Southeast Asia in 2018) is the dominant rideshare platform in Vietnam, covering motorbike taxi (GrabBike), car (GrabCar), food delivery (GrabFood), and grocery delivery (GrabMart). Fares are fixed in advance; no negotiation. GrabCar is the safest non-motorcycle option for daily transport.
⚡ Without Grab: reliance on negotiated taxis with higher risk of overcharging, language barriers and no journey tracking.
✅ Install Grab before or immediately upon arrival. Link a payment card or use cash. Use GrabCar (not GrabBike) if you prefer a car. Enable trip sharing to send your live location to a contact.
VssID App: Track Your BHXH Social Insurance Contributions
The VssID app (Vietnam Social Security Digital ID — available on iOS and Android) allows you to view your BHXH contribution history, check BHYT insurance status, and access your social insurance book digitally. It is the official app of the Vietnam Social Insurance (BHXH) agency and is updated monthly.
⚡ Without VssID: you cannot verify that your employer is actually paying your BHXH contributions (some employers deduct but do not remit). Unpaid contributions affect your lump-sum refund amount when leaving Vietnam.
✅ Download VssID from App Store or Google Play. Register using your BHXH number (obtained from your employer or BHXH office) and CCCD/passport. Check contributions monthly — if months are missing, contact your employer HR immediately.
Vietnam's Three Climate Zones: Plan Accordingly
Vietnam spans 3 climate zones: (1) North (Hanoi): 4 seasons — hot/humid summer (May–Sept), cool/dry winter (Nov–Feb, can drop to 10°C in Hanoi). (2) Central (Da Nang, Hội An): hot/dry (Jan–Aug), heavy typhoon season (Sept–Dec). (3) South (HCMC): two seasons — hot/dry (Nov–Apr) and hot/rainy (May–Oct). The Mekong Delta floods May–November.
⚡ Inappropriate clothing, no rain gear, or travel to central Vietnam during typhoon season without monitoring forecasts.
✅ Pack for the specific city and season of arrival. Bring a quality rain jacket (not umbrella — impractical on motorbikes). For Hanoi winters: bring a warm jacket (10–15°C possible January–February). Monitor nchmf.gov.vn for typhoon alerts if in central Vietnam July–December.
Face-Saving Culture: Avoid Public Confrontation
"Mặt mũi" (face) is central to Vietnamese social dynamics. Publicly criticising, embarrassing or contradicting a Vietnamese colleague, landlord or official — especially in front of others — causes deep offence and typically makes resolution harder, not easier. Complaints and disagreements are much more effectively handled in private and indirectly.
⚡ Damaged professional and personal relationships; counterproductive outcomes in negotiations, dispute resolution and workplace dynamics.
✅ Address problems privately and diplomatically. Frame complaints as "working together to find a solution" rather than assigning blame. Accept that "yes" may mean "I heard you" rather than agreement. Build rapport before raising issues. Patience and indirect communication resolve more problems than confrontation.
Vietnamese Coffee Culture: A Daily Ritual Worth Embracing
Vietnam is the world's second-largest coffee producer and has a unique coffee culture. Cà phê trứng (egg coffee), cà phê sữa đá (iced milk coffee), and ca phe den da (black iced coffee) are local specialities. Cà phê is a social ritual — business relationships are built at neighbourhood cafés (quán cà phê), not in formal meeting rooms.
⚡ Missing an important cultural bonding ritual that opens doors in business and personal relationships.
✅ Accept coffee invitations from Vietnamese colleagues and contacts. Learn to order: "Cho tôi một ly cà phê sữa đá" (iced milk coffee please). Visit the famous egg coffee cafés in Hanoi (Giang Café, Đinh Café). Explore local coffee culture — it is one of the most rewarding aspects of life in Vietnam.
Motorbike Parking: Always Use Official Parking Areas
Parking on footpaths (sidewalks) in central Hanoi and HCMC is increasingly enforced — motorbikes and cars parked illegally may be towed under Decree 168/2024. Official parking lots (bãi xe) charge VND 5,000–20,000 for motorbikes. Many restaurants and cafés have associated parking boys (bảo vệ) who manage a fee parking area.
⚡ Vehicle impoundment with fine VND 300,000–400,000 (motorbike) for illegal parking. Towing fee additional.
✅ Always park in official designated areas. Pay the parking attendant on arrival (VND 5,000–15,000 typical). At markets and commercial areas: follow signage to bãi xe. Never block fire hydrants or government building entrances.
Reducing Plastic: Bring Your Own Bags and Reusables
Vietnam has a significant plastic waste problem — single-use plastic bags and takeaway containers are ubiquitous. While formal recycling infrastructure is limited, Vietnam is implementing a plastic bag tax and many international-standard supermarkets charge for plastic bags. The informal ve chai (waste collector) system does recycle metals, paper, and some plastics.
⚡ Contribution to local environmental impact; minor costs from plastic bag charges at modern supermarkets.
✅ Bring a reusable shopping bag (túi vải) — available at WinMart, AEON, and supermarkets for VND 5,000–15,000. Carry a reusable water bottle and use filtered water refill points. Use the ve chai system: set aside clean paper, plastic bottles and metal for the ve chai collector who visits regularly.
BHXH Pension Lump Sum: Plan Your Exit Timing
Foreign employees who contributed to BHXH (social insurance) are entitled to a lump-sum payout when their work permit expires or they leave Vietnam permanently. For 3 years of contributions at VND 25,000,000/month average: lump sum ≈ VND 112,500,000 (≈USD 4,500). The payout is subject to 10% PIT withholding. You cannot claim until your work permit has expired or been formally closed.
⚡ Missing out on a significant cash benefit by not planning the exit process correctly; inability to claim if work permit is still valid at time of departure.
✅ Plan your departure timeline to allow 2–4 weeks after work permit expiry to process the BHXH lump-sum claim at the provincial BHXH office. Download form Mẫu 14-HSB from baohiemxahoi.gov.vn. Use VssID app to verify your total contribution history before applying.
Tet Gift-Giving and Red Envelope Customs
Tet (Lunar New Year) gift-giving is an important social and business custom in Vietnam. Common gifts: fruit baskets, premium tea, coffee, alcohol (Johnnie Walker, imported whisky), and bánh chưng (sticky rice cake). Lì xì (red envelopes with money — typically VND 100,000–500,000 per child) are given to unmarried children and elderly relatives. It is appropriate to give gifts to your direct supervisor, key business partners, and household staff.
⚡ Missing a key relationship-building opportunity; appearing inconsiderate in Vietnamese social and professional contexts if gift-giving is entirely ignored.
✅ Budget VND 200,000–1,000,000 per colleague/partner for a Tet gift basket (available at WinMart, AEON, and specialist gift shops from January). Give lì xì to children of Vietnamese friends and colleagues. Do not wrap gifts in black or white paper (funeral colours). Express new year wishes: "Chúc mừng năm mới" (Happy New Year) and "Chúc sức khỏe" (Good health).
English Signage is Limited Outside Major Cities
While English is well understood in hospitality and international business in HCMC and Hanoi, English signage is sparse in residential areas, at government offices, on road signs outside tourist zones, and in markets. Vietnamese administrative forms are often Vietnamese-only. Outside major cities, English may be minimal even at hospitals.
⚡ Navigation difficulties; difficulty at government offices; risk of misunderstanding administrative requirements.
✅ Install Google Translate with Vietnamese downloaded for offline use (camera translation mode is very effective for menus, signs and forms). Save the Vietnamese names of key destinations on your phone to show to Grab drivers or taxi drivers. Learn 20–30 key survival phrases in Vietnamese. Use a bilingual Vietnamese colleague or friend for important administrative visits in the first months.
HCMC Metro Line 1: Now Operational (December 2024)
HCMC Metro Line 1 opened in December 2024, running from Bến Thành station (District 1) to Suối Tiên terminus (District 9/Thu Duc). 14 stations, 19.7km, fare approximately VND 7,000–20,000 per journey. Connecting routes link to bus networks. The metro is air-conditioned, punctual, and avoids traffic — a significant improvement for commuters in the eastern corridor.
⚡ Expats unaware of the metro continuing to pay for Grab or taxis for routes now covered by the metro at a fraction of the cost.
✅ Download the Metro HCMC app to view timetables, maps and purchase tickets. Use the QR code payment system on the metro gates. Check if your workplace or home is within walking distance of a Line 1 station. Line 1 operates approximately 05:30–22:30 daily.

GDT tax enquiries — 1900 558 838. BHXH enquiries — 1900 9068. International operator assistance — 110. Vietnam Airlines — 1900 1100.
⚡ Delayed response to emergencies due to not knowing correct numbers in advance.
✅ Save these numbers in your phone contacts before your first week in Vietnam. Keep a small card in your wallet with at minimum: 113 (police), 115 (ambulance), your international insurer hotline, and the nearest major international hospital emergency number.
Natural Disaster Preparedness: Beyond Typhoons
While Vietnam is not located on a major tectonic fault, minor earthquakes occur in the northwest (Điện Biên, Sơn La) and occasionally in other regions. More practically relevant: (1) Fire safety in older apartment buildings — Vietnam has had several high-rise residential fires. (2) Industrial pollution incidents near chemical facilities. Preparations are similar for all these scenarios.
⚡ Unprepared response to natural or industrial emergency; unfamiliarity with building evacuation procedures.
✅ Before signing a lease: ask about the building's fire alarm system, sprinkler coverage, and evacuation exits. Know where the fire exits are on your floor. Keep an emergency bag (passport, cash USD 200+, medication, power bank) ready. Register with your home country embassy for emergency notification.
