my visa was late coming, I came got 30 days on entry, the next day went to my local imagration office and extended for 30 days,
Imagration officer said next time you come I could extended for 60 days based on marriage, then if you have the funds in a thai bank account, you could do the 1 year marriage visa, my visa came same day as I went to imagration, so I'm not going to abuse the system with any more extension, I'm going on holiday next month and renter to activate my visa,
If you have not got a long history of extention don't worry.
but we don't know on what grounds ,if he's be sticking to the law getting a visa every time he comes ,and the odd extension why can you think of a reason, and don't say imagration can refuse you entry at the airport, he hasn't got that far yet
makes no difference how many visa he's had as long as he's had a visa,if he's gone through the right process, by getting a visa before coming why should they not approve,
why not go into your local government registry office, the same office you go to for birth certificates, and ask them for advice, could point you in the right direction, never know unless you try.
