What should I do about my OA retirement visa after leaving Thailand without a re-entry permit?

it appears that the 90 days Single and 1-year Multiple Entry Non-Imm-O Visa for the purpose of retirement, has been discontinued by the embassy in Washington DC and all consulates of Thailand inside the USA

You have a couple options

Okay what I believe is happening here is a misuse of terminology :O AND the perils it causes when asking questions.

Let's take a minute and go over the difference between a VISA sticker and an entry stamp.

A visa is a sticker (usually from a thai consulate in another country which has an issue date, a valid until date and is sold either as a single or multiple entry.

The ENTRY stamp you get from a visa is what let's you stay IN thailand. The visa only allows you to get in for xxx days depending on the visa type. A visa can expire yet the entry stamp you get from the visa is still valid.

IN the instance of this O/P we have an O-A visa evidently issued in Aug 2018 with a valid until date of Aug 2019. That visa is good for unlimited entries during it's validity and each entry gets you stamped in for a WHOLE new year.

I believe the O/P did NOT extend their visa (which you can only be done at an immigration office BUT actually exited and re-entered the country just before the visa itself expired to get a whole new year's entry stamp taking them to Aug 2020.

The thing IS that O-A visa had a "built in" re-entry permit when it was sold (it was sold as multiple re-entry) BUT that re-entry feature is ONLY valid for the length of the visa (in the O/P's case until Aug 2019.

SO even though they had an ENTRY STAMP allowing them to stay IN thailand until 2020, if they wanted to leave and come back and get stamped in until that date again (wanted to keep that entry stamp 'alive' while they were out of the country) they would have had to BUY a re-entry permit before they left the country. Otherwise that entry stamp (the actual stamp that lets you stay IN thailand) canceled when you stamped out of the country.

@Ri**

correct me if I'm wrong on any of this please as far as what you did

Usually there will be a rectangular red notice stamp in your passport beside your extension of stay stamp warning you to get a re-entry permit to keep your stay alive.

Your OA visa WAS multiple entry while it was valid

A re-entry permit keeps your admitted to stamp alive

Your permission to stay, and your visa, are now things of the past. You will need to start again. If you arrive in Thailand without a visa you will get the 30 day visa exempt entry.

As mentioned above, and in this group many times before, re entry permits should be bought before you leave in order to keep your permission to stay valid. If that’s not done your current permission to stay ends when you leave.

Re-entry permits have to be purchased BEFORE leaving. You have to start again I think.
