in order to stay in Thailand on the reason married to a Thai wife, you need the 90-days Non-imm-o family visa, which must be followed by the 1-year Extension of Stay Permit. You need to prove either 400.000.- THB in a Thai bank account in your sole name, or an affidavit of income from your embassy over a minimum of an income over 40.000.- THB per month

normally for 4 weeks

@John *******

you must be a very confused man. Brandon's advice is spot-on and 100% correct

@Robert ********

not the same thing. You do a "visa run" in order to apply for a visa at a Thai consulate. You do a "border run" when you just "bounce" at a border and re-enter visa-exempt (not "except")

no Thai Immigration office will offer you any of their service if you haven't been TM30 registered yet

@Jason ********

and apart from the TM30 registration, you will need to fulfill the financial requirements needed for a "1-year EOS" out of a 90-days Non-Imm-O retirement visa. If you are a citizen of a country whose embassies in Thailand do not issue income affidavits any more, your only choice in the first year is a proof of a deposit of a minimum of 800.000.- THB in a Thai bank account in your sole name. And on the day you apply for the Extension, you need the bank letter that proves the money has been sitting in your account for a minimum of two months

@Jason ********

you should be well aware that there is absolutely no Thai Immigration out of the 85 Immigration offices in Thailand, who will allow you to apply for the "1-year Extension of Stay Permit" based on retirement, if you haven't already been registered by a TM30. They won't even start to service you without one

@Robert ********

there is no need to do a "visa run" and apply for a tourist visa on a Thai embassy in a neighbour country. A "border run" is enough to get them a visa-exempt 60-days stay permit

At Customs, you better walk through green and show them nothing. But before you walk through Customs, you need to pass Immigration. There you show your passport (must stil have a minimum validity of 6 months) and you will get stamped in on a visa-exempt entry with a 60-days stay permit. Sometimes Immigration wants to see your boarding ticket. i.e. the flight number you arrived with. ALWAYS check the stamp immediately for the 60-days count, on the spot, as Immigration officers are humans as well and humans sometimes tend to make mistakes

David Chinnery you CAN apply for the "change of visa type" from a tourist visa or a visa-exempt entry, to the 90-days Non-Imm-O retirement visa, after you arrived, on Immigration inside Thailand. The requirements are posted on the Immigration website under Number 9 .. click onto it, a pdf will open. Most important requirement is a bank account, a deposit of 800,000.- THB minimum, and a rental contract
