What are the main differences between the Non-Immigrant O (Pensioner) and Non-Immigrant O-A (Longstay) visas in Thailand?

And how many newcomers are not aware of what you just wrote

The 2000 Baht fine is a consequence - sometimes from. ignorance

Moot except to naive people we see again and again on O-A and METV Visas who think that a 6 month or one year stay means come in a stay

I think it's not at all relevant to talk about 90 day reporting on this visa. Anyone that stays 90 days on ANY visa in thailand does 90 day reporting so it's a moot point as far as relevance to holding a Non-O-A visa.. You stay 90 days you file a 90 day report, you don't stay 90 days you don't file one.

On a year long, multi-entry Type O-A visa you are stamped in for a calendar year EVERY time you enter the country for the validity of the visa (a year from the date it's issued).

if have multientry visa valid for 1 year ,so how many time we can use tht visa?

Ellie - the O-A visa is Multi-Entry in the First Year - upon Entry into Thailand you get a permission to stay of 90 days. You must either Exit again or make a 90 day Report to Thai Immigration. The - Stays are 90 days each but the total length (term) of this Visa extends out to 24 months. As far as I know the O-A visa is the only Visa that works this way allowing the option of Exiting and Reentering or a Report at Immigration each 90 days. A final Exit and Reentry done a day or two before the First Year Expiry date takes the Term - Life of the Visa out to another 12 months. Each stay within the life of this Visa is 90 days.

hello have a good day ,i have 1 question if some one not mind can i ask ?

In the Second Year the O-A is no longer a Multi-Entry Visa. If you want to leave Thailand in the Second Year - you must purchase a Reentry Permit before leaving Thailand to preserve the Extension period of the O-A Visa.

The nice thing about the Non Immigrant O-A Visa is that last available Exit and Reentry into Thailand in a few days before the First Year Expiry (Enter before Date) - this assures nearly one full year of Extension.

As is turns out (in my opinion and estimation) people holding O-A Visas most often opt to just do 90 day Reports (in the First Year) instead of Exiting and Reentering Every 90 days

Hands down a year-long, multi-entry Non Immigrant Type O-A is worth it's weight in gold over a Non-O visa OR a yearly extension of stay.

That O-A visa is good for a year from the date it's issued. It is good for unlimited entries/exits to thailand with each entry getting you stamped in for a completely new calendar year (which means you can wring TWO years of stay out of a one year visa).

True it can only be gotten from a thai consulate in your home country (or one you hold legal residence in) and it does require a medical certificate and a police back ground check BUT as far as financial requirements you can meet them with your account in your home country (meaning you don't need to open an account here).
