Do I need to leave Thailand every 90 days with a Non-Immigrant O-A Long Stay visa?

If you travel in Thailand do you have to file TM 30 when you return to your house

Note that a 90-day report is something you do when you are in Thailand 90 continuous days. If you leave and re-enter before 90 days then 90 day clock resets to day 1.

One thing, Many people who have that visa seem to get stamped in wrong when they enter thailand. Make SURE that you get stamped in for a whole year when you enter the country. :)

Okay IF you got a year-long, multi-entry Non-Immigrant Type O-A (Long Stay) visa from a thai consulate in your country BEFORE you come here; the visa is good for a year from the date they issued it, it's good for unlimited entries to thailand for that year and every entry will get you stamped into the country for a full calendar year.

You do NOT leave the country every 90 days. If you're in thailand on the 90th day you go to the immigration office and file a TM47 <- 90 day report. That's it.

Perfect visa ! Also not forget the TM30 notification if you don't stay in a hotel. And don't forget to leave Thailand and come back just before your visa expires. You get a free year of stay at entrance. Then, you only need a re-entry permit to keep that free year alive should you want to leave Thailand and come back again in that year. Good luck over here !!!

With a NON-OA you report 90 days.

You can easily see on your entry stamp that admitted to stay is one year from arrival.

Every 90 days.
