Moving to Thailand: A First-Steps Guide for Expats

Thailand has been a destination for foreign residents for decades, and the result is a visa landscape more varied and more confusing than almost anywhere else - retirement extensions, marriage extensions, education visas, business visas, a membership programme, a newer long-term resident category, and the well-worn tradition of leaving the country periodically to reset a permission to stay.

That last option is why a lot of people live here precariously. The purpose of this post is to point you at the routes that are actually stable.

The routes worth using

Retirement extension. For those over a qualifying age who can show either a monthly income or a deposit held in a Thai bank account, with conditions about how long the funds must be held. It is the most-used long-stay route and it is well established. Requirements have been tightened over the years, particularly around maintaining the deposit and around health insurance for some categories, so verify current terms.

Marriage extension, for those married to a Thai national, with its own financial requirements.

Long-Term Resident (LTR) visa. The more recent and genuinely significant addition, offering a long validity to categories including wealthy global citizens, wealthy pensioners, work-from-Thailand professionals employed by established foreign companies, and highly skilled professionals - with a digital work permit and tax advantages for some categories. If you qualify, this is a substantially better position than the older workarounds, and it is the route to investigate first if you are a remote professional.

Thailand Privilege, the membership programme offering long-stay privileges in exchange for a substantial fee across several tiers. Straightforward and expensive.

Business visa and work permit, where a Thai employer or your own Thai company sponsors you. Work permits have specific requirements including, in many cases, ratios of Thai employees.

Education visa, commonly used for language study, which has been subject to more scrutiny where it is used primarily as a residence device rather than for genuine study.

What I would steer you away from is building a life on repeated tourist entries and border runs. Enforcement has tightened, entry is at the discretion of the immigration officer, and it accumulates nothing. The Thailand visa section covers the current routes, and the general principle that a visitor allowance is not a residence strategy is in visas and residence permits explained.

The work permit question

This deserves stating clearly because it is widely misunderstood. Working in Thailand generally requires a work permit, and the definition of work has historically been broad enough to encompass activity performed in Thailand even where the client or employer is entirely abroad.

For years a large population of remote workers operated in the ambiguity. The LTR work-from-Thailand category and the associated digital work permit exist precisely to resolve it, and if you qualify, using a proper route is worth the effort - the general considerations are in working remotely for a foreign employer and digital nomad visas in 2026.

The tax side has also been changing. Thailand has revised its approach to taxing foreign-sourced income remitted into the country, which materially affects long-stay foreign residents living on foreign income. This is a live area and precisely the kind of thing where old advice is dangerous - get current advice from a Thai tax professional. See tax residency explained and the Thailand tax section.

Arriving and staying legal

Two obligations catch people.

90-day reporting. Foreign residents on long stays must report their address to immigration every ninety days. It can often be done online but the online system is not always reliable, and missing it results in a fine. Put it in your calendar.

TM30 address notification. The property owner or manager is required to notify immigration of a foreign national staying at the address. In practice the burden often falls on the resident to ensure it has been done, and it can be requested when you deal with immigration for other purposes.

Neither is difficult; both cause problems when ignored. The general approach in dealing with bureaucracy abroad applies, with the addition that Thai immigration practice can vary noticeably between provincial offices.

Opening a bank account has become harder for foreigners without a long-stay visa and work permit, and the requirements differ between banks and branches - persistence and the right documents matter.

Healthcare

Thailand’s private hospitals in Bangkok, Chiang Mai and Phuket are excellent and are a major medical tourism destination, with internationally trained doctors, English-speaking staff and costs far below Western levels. This is a genuine attraction and a large part of why the country works for retirees.

Foreign residents generally use private care and hold private health insurance. Some visa categories require it, and requirements have been introduced for certain retirement categories. Note that insurance for older applicants becomes expensive and pre-existing conditions are commonly excluded - arrange cover before you need it rather than after, per health insurance for new arrivals.

The public system exists and is inexpensive but is generally not the route foreign residents take. Details in the Thailand healthcare section.

Cost of living and where to live

Costs are low by Western standards, particularly outside Bangkok’s expensive districts. Food is inexpensive and superb, transport is cheap, and services are affordable. Imported goods, cars and alcohol are taxed heavily.

Bangkok is a huge, hot, energetic city with excellent transport in the areas the sky train and metro serve and difficult traffic elsewhere - where you live relative to a station matters a great deal.

Chiang Mai in the north is cooler, cheaper and has a long-established foreign community, with the significant caveat of a severe seasonal air pollution period from agricultural burning, which is a genuine health issue and drives many residents away for those months.

Phuket, Koh Samui and the islands are beautiful, expensive relative to the mainland, and seasonal.

Property: foreigners cannot generally own land, but can own condominium units subject to a quota on foreign ownership within each building. Arrangements used to work around the land restriction - nominee structures, long leases - carry legal risk and require independent advice, not the developer’s lawyer. See buying property as a foreigner.

Language and daily life

Thai is tonal, which is the main difficulty for learners, and uses its own script. English is common in tourism, in international business and in the expat-heavy areas, and much less so in administration and ordinary life.

Even basic Thai transforms daily interactions, and Thai people are notably encouraging towards foreigners who try. See learning the local language fast.

Socially, Thailand is welcoming and the foreign communities are large and long-established, particularly of retirees. The flip side is that those communities can be insular, and the distinction between living in Thailand and living in an expatriate enclave inside it is sharper here than in most places.

Climate is hot year-round with a rainy season, and the heat and humidity are a real adjustment rather than a holiday feature.

What catches people out

Building a life on tourist entries and border runs. Missing 90-day reporting. Assuming remote work needs no permission. Changes to the taxation of foreign income remitted into Thailand. Chiang Mai’s burning season. And bank account difficulties without the right visa status.

For regional comparisons, moving to Singapore is the expensive, orderly alternative, moving to Vietnam and moving to the Philippines are the cheaper neighbours with very different permit systems, and moving to Japan offers a very different Asian proposition with a stronger residence framework.

Regional detail, current visa routes and cost breakdowns are in the Thailand country guide and the cost of living section. Because Thai immigration and tax rules have been changing, the retirement abroad forum and the wider forum are worth checking for how the rules are actually being applied right now.
