never go into an overstay knowingly! Avoid it !

change your home branch. Get your TM30, visit Immigration and ask them for the certificate of residency. Then visit the bank branch and ask them to update your address and phone number. Done

yes, every U.S. Dollar has double the purchase power in Thailand. You pay less than half for rentals, local food, electricity, water, carwash and restaurants, just to name a few.

The banking rules have changed since February 2025. No more account opening on touristic entries

@Dave *******

I know all that. And you are still in the wrong. In order to be able to apply for the initial 90-days Non-Imm-O visa inside Thailand, by the "change of visa type" from a touristic entry, you need the 800,000 TH already parked in your Thai bank account on the day you apply for the"change". It means - you already need to have a Thai bank account. If you do not have one, you are in a CATCH22 situation. No Non-O visa, no bank account opening. The banking rules have changed since February 2025. No more account opening on touristic entries

He received a 90-days admitted stay permit stamp upon entry, based on a 90-days Non-Imm-O Retirement Visa he got issued outside of Thailand.

This red stamp itself is not a visa. This stamp is a 90-days stay permit you get stamped when you enter Thailand on a 90-days Non-Imm-O visa.

The stamp just indicates the “admitted until” length of stay – here 90 days - based on entering on a single entry 90-days Non-Imm-O visa.

The visa itself, when he entered Thailand, has changed its status to USED and is not valid anymore.

The visa got issued in the shape of a .pdf document which got mailed to the applicant by the processing Thai embassy. You could print out the visa document and show it

The entry stamp just indicates the admitted length of stay (90 days) based on the single entry Non-Imm-O visa, but it clearly says on which visa-class you entered in the upper right corner

Some bank clerks just are too lazy or don’t have the slightest idea how to service foreigners who want to open a Thai bank account. They will often invent any rules or excuses in order to get rid of you.

@Dave *******

there is only one agent in Bangkok who claims they can still open a Thai bank account for people who entered on a touristic entry. The downside is, they only do it if you buy their complete package: the "change of visa type" to the initial 90-days Non-Imm-O visa, and the subsequent 12-months extension of the stay permit. Their price is 55,000 THB

@Dave *******

you cannot "switch" from a touristic entry to a Non-O visa without already having a Thai bank account and already holding 800,000 THB in it. As you can't open a Thai bank account on a touristic entry anymore, the answer is NO, you can't
