There is no such thing as "retirement visa", nor a 15 months stamp. You got a 3 month non-o visa then you got a "retirement extension" for an additional 12 months. 3+12=15. You are confused by the semantics and your lack of knowledge of the Thai system. A valuable lesson in life is that if you don't know something, always be humble and willing to learn.

@Todd ********

That's not true. Same with Covid extension, we will only know a day or two in advance.

@Megan *******

You don't know what you signed for, hence your "in between" confusion. You didn't enroll in a language school. Your agent used a random school as third party for you to get a "under the table" (bribery) ed visa. The agent is doing the 90 days report every time by himself to make sure that you are not tested. The issue here is not being here for a year, the issue is having a under the table visa in your passport. If you enter by land border, you won't have issue, except just avoid Poipet border, they are annoying. If you enter by air, avoid BKK airport, they are notorious for giving people on under the table volunteer and ed visa trouble.

@Megan *******

There is no such thing as an "in between". Either you got it from an agent or not. From your answer, it's obv u use an agent or u would have been tested every 3 month.

I'm Canadian, no need. Russian? Not sure. But you did a good thing by asking because a lot of visa agents might lie so you can become a customer. It would not surprise me that Russians need proof of funds, for obv reasons. I'm sure some here knows.

@Zou ******

Don't ask if you are going to argue with the answer :)

I converted my Volunteer visa to a Marriage extension with an agent without leaving Thailand. For your situation, you can border-run Laos, they do not care about your visa history. Avoid coming back by air, they will give you trouble, but border runs no problem. I say Laos because they are notorious for not giving anyone problems.

How much is 3rd party insurance?

No idea, but I would expect around 300 baht. I'm sure some people here would know.

A fixer is basically a bribe. You pay him some money for the peace of mind of not getting quizzed.
