Will my Non-B visa extend by 9 months or 12 months after my initial 90 days?

IF that's the case

@Benner *********

, then when you have 45 days or less left on your current 90 day stamp you take MORE documentation from your employer go back to Chaengwattana and apply for a year extension,

if you're teaching you'll do it in Section N, if you're working for a company in a position OTHER than teaching you will use Section M

You'll apply, pay the 1900baht, get a 30 day under consideration stamp, and then after that stamp runs down you go back and get the year extension inked into your passport

That's what it is! lol

Is your passport or contract only for 90 days? Seems strange that they only gave you 90 days
