Same stage as you, same inbox habit. My wife's went in a couple of weeks before Ada's, so I'll report back when anything moves.
Ada, my wife, did her biometrics for the dependant visa last Tuesday. The appointment itself took twenty minutes and the staff were lovely. Now we're in the part nobody describes properly: the silence.
The official page gives a processing range, and I know it's only a range. But I'm checking my email like it owes me money, and she has already started telling her employer back home that she might leave "soon", which is not a date anyone can plan around.
For those who've been here: after biometrics, how long did it actually take before you heard anything? Did you get any updates in between, or was it silence until the decision? And did anyone chase it, and did chasing help or just annoy people?
