Will leaving Thailand with a single-entry Non-O visa affect my visa status?

Peter Norris no multi any more. Purchase a re-entry permjt at the immigration office at the airport and come back before your 90-day visa expires so you get your 12-month extension

Peter Norris . .to answer your question, you got stamped in for a 90-days stay permit. You can buy a single re-entry permit for these 90 days for 1000 Baht on Immigration, and exit Thailand for a while, but you need to be back in time to apply for the 1-year extension of stay (since this is your original plan). The re-entry permit only keeps the 90-days stay permit active, and not any day longer.

get a re-entry permit

But can you still apply for a re-entry permit during the first 90 visa period, before applying the 12 mths temporary stay permit.

You just need to go to your immigration office and get a single entry, 1,000 baht, if you don’t plan on coming and going a lot it’s cheaper to get a single entry

Talk to Thai Visa Centre

Get a re entry permit (single) before u leave come back before the 90days end and apply for your 1yr extension....after u get your 1yr extension then get a re entry permit (multiple) it will expire same time as your 1yr extension

I did this recently with no problem. Buy a re-entry permit at your local Immigration office or at the airport before departing through Immigration.

Peter Norris . . .Please use correct terminology.

You won’t be applying for a “12 month multi entry non o retirement visa”.

Thai embassies all over the World discontinued issuing “12 months multi entry Non-Imm-O Retirement Visa” in October 2023.

You enter Thailand on the 90-days visa. You will get stamped in for a 90-days STAY PERMIT. The VISA itself becomes invalid upon entry. You are then in Thailand on a STAY PERMIT.

You will apply on Immigration for the “1-year extension of temporary stay permit based on retirement”. The extension is not a visa. The extension is a stay permit. For this "one year extended stay permit" you are going to buy a multi re-entry permit for 3800 Baht, because during the one-year stay permit you plan to exit and re-enter Thailand more often than three times (if less often, then a single re-entry permit for 1000 THB would be sufficient)

Immigration in their insufficient English call this a “visa extension”, ignoring the fact that they technically don’t extend any visa, but the stay permit.

That 90 day Non-O visa is your retirement visa. You would be applying for a 12 month extension of stay based on retirement, with a multiple re-entry permit.

As to leaving in the initial 90 day period you would need a re-entry permit to keep that visa alive and be back before the date of the current entry stamp in your passport

No more Multi entry, They canned it, you need to get a reentry permit before you leave, You should be able to sort it before leaving or at the airport
