Hello! I'm a Dual US citizen and Thai National, wife (US citizen) just got approved for her 90 day Visa Non-O through marriage, should we go to the govt office when we land in Bangkok to extend it for a year, or wait closer to the end of the 90 days (I originally thought we got a year when it was approved, but guess not)? Also, what exactly do we need to provide for info when we go?

Thanks ahead of time.
