Will I get another 90-day entry stamp if I leave Thailand with a one-year multiple-entry Non-O visa?

Okay, IF the visa is indeed a year-long, multi-entry Non-O visa which only you can tell seeing as it's in your passport, it would be unlimited entry (multiple) for the duration of the visa (a year from the issue date).

When this 90 day stamp is running out, go to the border, stamp out of thailand, stamp in&out of another country and then right back in to thailand to get a new 90 day stamp.

You do that for the whole year the visa is good for every 90 days and you can get 15 months of stay out of that visa.

Normally, I'd say "bounce out and get another 90 day stamp", but with these visas not being issued any more from the UK, I'm concerned.

1. Do you have a single entry Non-O and you have an extension of stay on it?

2. If you have a multiple entry Non-O, did you get it from some other place (i.e. Savannakhet or HCMC)?

Edit: If you didn't get it from the UK after all, but instead Gibraltar, I'm assuming it is an actual multiple entry Non-O, and you can bounce in and out of Thailand anytime you want. Whenever you bounce back into Thailand, you'll get another 90 day stamp.

Can you post a picture of the visa? I'm intrigued as multiple entry Non O visas haven't been issued since 15th June 2019 in the UK

Yes that's exactly what you need to do every 90 days
