It must match your passport

@Greg *******

I know Chiang Mai make their own rules on TM30. I exited last year with a re-entry permit and my friend was on a visa-exempt. When we returned (staying at the same address) we both went to immigration to re-register our TM 30 and the head woman (Nakhon Sawan office) said I don't have to re-register because I'm still on the same permission to stay (marriage extension) but my friend has a new permission to stay so has to re-register. The same is true of METV. They also have to re-register on every entry because it is a new permission to stay which is what happens with a DTV.

@Karsten *******

This is the rule for all visas, with exception being those on extension of stay based on marriage or retirement. These people can buy a re-entry permit which keeps their TM30 alive. All other visa holders have their permission to stay cancelled when they leave and have to re-register their TM30 upon their return even if they are staying at the same address.

He can use his non-O anytime before 10th Oct, and this will activate his 90-day single entry.

Your 90 non-O visa does not activate until you enter the country, and this has to be done before 10th Oct 2025. You can also apply for a 60-day extension based on visiting your wife without providing any financial proof. You can also request a 12-month extension, which has to be done within the last 30 days of your initial stay. For this, you need 400k baht in a Thai bank account in your name, and the funds must come from outside of Thailand. Once you have applied for this, you will get an under consideration stamp in your passport. This is usually for 30 days, but can be 60. During this consideration period, you can purchase a re-entry permit, allowing you to leave Thailand and return without obtaining another visa.

@Allan ******

It is currently 60 day visa-exempt

@James ******

and you never get a receipt for this payment

James Green: The certificate is free, but offices are allowed to charge up to 500 baht for expedited issuance.
