QUESTIONS...

 

A) In order to apply for EXTENSION IN THAILAND, I will need 400,000B or 40,000B/Month income + Health Insurance coverage, correct?

 

B) What do I do with the return ticket, if I stay longer than a year?  Most airlines charge money to change a flight.  Do I ask for a refund minus the change fee?

 

C) If I do stay in Thailand on a Non-Immigrant Visa Category “O”, Marriage, Annual extensions and I want to go back to America and WORK for 6 months - year (consulting work, can't be done remotely in Thailand, need to be on site in America), does that invalidate my O visa? 

 

D) Seems like I read there is some kind of exit paperwork to fill out? 

 

E) What if I stay outside Thailand more than a year?  Will I need to start the process all over again and apply for a new "O" marriage Visa in America again?

 

Thanks in advance for your help.

 

A. You need 400k baht in a Thai bank for 2 months or proof of 40k baht income. No requirement for insurance.

B. A return ticket is not required. A one way ticket to a nearby country from any airport here will be accepted.

C. Your extension of stay would remain valid. You would need a re-entry permit to keep it valid when you enter the country. You only have to be here long enough to apply for a new extension.

D. Not needed. Just a re-entry permit is needed before you leave.

E. You would have to start all over again. You would need a new non-o visa but you can get one at a nearby embassy or consulate.
