Will I lose my student visa if I leave Thailand for 2-3 months due to an emergency?

I just extended my ED visa for 90 days on April 11, and the cost was 1900 baht. Not Samui office, but I’m not sure why it would be different. My extension was stamped until July 15. I may have to leave the country in June because my kids visas expire, but I’m going to get a letter from my school, pay for a re-entry permit, and hope for the best. As long as my extension doesn’t expire while I am gone, I’m counting on being able to stay in good status with my ED visa. Maybe you can do this too.

Okay I think by now we understand that you're current stamp is good until April 30th.

Why would you pay 3000baht for an extension when the price is 1900baht?

IF you want to return on the ED visa (or extension) you would go get it extended 90 days, then get a single re-entry permit for 1000baht. That way when you return in 2 months you'd be stamped back in for the expiration date you got after the extension.

As Robert pointed out, you could be questioned by immigration officers WHY you're on an education visa but have been out of the country for the last 2 months.

Good Luck. (y)

Even if you are on a visa or 90 day extension, I am guessing 2-3 months out of the country and both will have expired. If by some quirk of fate it has not, be prepared to not get another extension or first extension, because you will have clearly not been attending classes.

The Visa is a sticker in your passport with some text, it does not change in different text when being abroad. IF you have a multiple entry visa you can come back till the enter before/vaild until date stamped on the Visa. IF your visa was a Single Entry or you already visited Immigration Office for an Extension of Stay you need a re-entry permit and come back before the date in the Admitted until stamp or Extension of Stay valid until stamp. If you come back after that date than you have to start all over again.

the real question IS, what is your current "admitted until" or "extension of stay valid until" stamp in your passport now?
