My Thai wife and I are going to the UK for a 2 week holiday later this year

She has had a Tourist visa before and 2 spouse visas before we deided to return and live in Thailand

Hopefully therefore I think she should get a visa easily

The question is after we hand the forms etc in, when normally will the visa be available to pick up - how long do we need to say in Bangkok

I assume it cannot be mailed

Any advice appreciated

Not sure what the current processing time is, but whilst the passport cannot be mailed VFS will courier it to various points throughout Thailand where it can be picked up, which will mean you don't need to wait in Bangkok.
