“You can extend your stay in Thailand over the original 90-day term with a Single Entry or Multiple Entry Non-O Visa by submitting an application at the closest Immigration Office. “
In the case of Single entry non o visa, is it only possible to extend for 30 days? In the case of multiple entry non o visa, is it possible to extend for 60 days?
So I cant get extend for a year? How about 3month??
This site is also confusing with conflicting information. Some people say you can do it with just a birth certificate, while others say you can't. An agent told me it can be done with just a birth certificate.
Now my visa is dependent visa I got in Vientiane, not for retirement.
If I go to the Udon Thani immigration office, could I possibly extend my one-year stay?
