How can I maximize my stay on a Non-Immigrant Type O-A visa in Thailand?

How to get the most out of a year-long, multi-entry Non-Immigrant Type O-A (Long Stay) visa.

First let's wrap our heads around this fact. A VISA does not let you stay IN thailand. :O The entry stamp you get off the visa does. All a visa does is guarantee that IF you're allowed in to the country you get in for the number of days allowed by that visa.

A year-long, multi-entry Non-Immigrant Type O-A (Long Stay) visa is ONLY available from a thai consulate in the country your passport comes. It requires a medical certificate, a police background check, proof of health insurance, but you can meet the proof of funds requirement by using a bank in your country.

The visa is good for a year from the date it's issued. It is good for unlimited entries to thailand during that time. Each entry to thailand will get you stamped in for a year (actually a year minus a day because the day you arrive is counted as day one).

To maximize the time in country on this visa you need to pay attention to the expiration date on the VISA itself (not your year entry stamp). Exiting and re-entering the country just before the "enter before" or "valid until" date on the VISA will get you stamped in for another year. <- This is the "free second year" people talk about on an O-A visa.

Keep in mind that IF you're going to exit/re-enter the country during this "second year" (after the VISA expired) you will need a re-entry permit to get stamped back in until your entry stamp expires.

As Gregor correctly pointed out in a deleted comment. In order to maximize your time here on this visa you DO need to meet the terms under which the visa was issued AND seeing as it's after Oct 31st that means mandatory health insurance is required. IF you try to stamp in on an existing non-O-A visa you need your health insurance to be valid for that year stamp you're getting OR you will only be stamped in until your health insurance runs out.

Thanx Gregor for bringing it to my attention. (y)

Let's see what really happens when people stamp in on O-A visas in the near future as far as whether the immigration officers at passport control follow the rule or not.
