Check again in May. No one knows if or when the ETA system will be put in place. It's currently on indefinite hold while they plan how to make it work.

If you don't have the money in your Thai bank account that you need to apply for the 1-year extension, then your only option is to leave Thailand and either return visa exempt if you are from an eligible country, or apply for a Thai visa in another country. Most of the Thai embassies in nearby countries are advising a 10-15 business day application time. You can check each embassy's website for their visa requirements and processing times.

You might be thinking of a multi-entry non-O visa. That is no longer available for quite a while now since the e-visa system became available.

The only multiple-entry retirement visa available now is the non-OA visa which requires much more than the non-O visa requires, including mandatory insurance, a health exam, a criminal background check and other items.

Most people get the single-entry 90-day non-O visa and then get a 1-year extension once they are in Thailand.

you're flat out wrong and people are denied entry for this every day. What you feel or believe is not relevant.

I tell people to follow the law

That depends on the embassy you use. Each embassy sets their own requirements. Some may require each person to have their own financial proof, while others might not require dependent visas to show proof.

what? That's literally the first question they ask when they're looking to deny entry. And they are denying entry to dozens of people per day. It absolutely happens daily. Cash or you're denied. In fact this is usually the stamp they use for denied entry regardless of the reason. At land borders they use this stamp without even asking to see the money, especially at Poipet.

@Ian ********

the 3 proofs are only for visa exempt generally

@Ian ********

you've been entering Thailand visa exempt for 30 years?

You will receive 60 days every time you enter Thailand.

You can leave and return as many times as they let you. There is no more answer than that. There is no rule or law that says how many times. It's at the discretion of the immigration officer. But they have become much more strict recently, and expect to be pulled out of line and questioned if you spent more than 3 or 4 months in Thailand.
