you still use wrong wording. . . . Immigration will not issue any "visa". They will issue a "-12-months extended stay permit". And you don't "move your visa" from the old passport to the new one. Immigration will only "move" the EXTENSION STAMP
you won't laugh any more when you find out that you cannot get a bank account opened on a touristic entry (which is needed for the retirement visa & extension)
depends on the bank staff, there are reports that applicants on a Non-O visa have been turned away. If this happens, pay an agent to get the bank account opened, it costs something around 5000 THB
the 90-days Non-Imm-O visa becomes invalid when you enter Thailand. You are in Thailand on a "stay permit". And only this stay permit can get extended for 12 months "based on having started on a retirement visa". You get issued a 12-months stay permit, not a "12 months retirement visa". Check this stamp - does it mention anywhere being a "visa"? No it doesn't. It is a stay permit
there is nothing such as a "12-month visa". There only is a 90-days visa, followed by a 12-months extension of a temporary stay permit. The 12-months extension is not a "visa". Your wording is wrong. There is no "15-months retirement visa", though. . . . Many Immigrations have by now discontinued using wrong English and don't talk about a "visa extension" any more. A "visa" cannot get extended, only a "stay permit" can get extended
having been on an ED visa before actually is BAD for your overall stay history. ED-visa are scrutinized, they make Immigration officials assume that you misused them for a longstay in Thailand. Be prepared to be approached in Thai language on Immigration! If you don't understand and speak Thai, you will have a very bad stance in front of them
as you are in Thailand on a tourist visa, you should get it extended with 30 days, and then apply for the "change of visa type" to the 90-days Non-Imm-O family visa. Because in order to be able to apply for the "change", you need a minimum of 15 days on your stay permit stamp. I do not know if this is possible from out of the 60-days extension of "family visit" as this one is not a touristic entry or touristic visa, and the possibility is not listed as being possible on the Immigration website regarding the "change of visa type". You could however visit and ask your Immigration, but it won't change anything in your situation other than you need to extend anyways, because you need those 15 days left on the stay permit, and you also need 400,000 THB in your Thai bank account on the day you apply for the "change", and you need a rental contract and you need to be TM30 registered to receive any service from the Immigration office
***exit Thailand, re-enter visa-exempt, apply for the "change of visa type" from the visa-exempt entry to the initial 90-days Non-Imm-O Family Visa on Immigration. The fee is 2000 Baht. The visa will get issued “under consideration” for 14 days. That’s why you still need 15 days on your entry stamp if you want to apply for the “change”
You need to show a minimum of 400,000 THB in your Thai bank account when you apply for the “change”
And you need to show a minimum of 400,000 THB having seasoned in your Thai bank account for 2 months to be able to apply for the “1-year Extension of Stay Permit”
TWO:
*** exit Thailand, visit any country anywhere in the World including your home country. Apply for the 90-days single entry Non-Imm-O Family Visa through the e-visa online system of the Thai embassy in this country. For this application you must prove that you physically are inside this country!
Wait in this country until the visa has been approved and issued to your email-box as a .pdf document. Print it and re-enter Thailand. You will get stamped in for 90 days
In most countries, you need to show a minimum of 400,000 THB in your Thai bank account for the last three months, when you apply for the 90-days Non-Imm-O family Visa
And after having entered Thailand on the Non-O visa, you need to show a minimum of 400,000 THB having seasoned in your Thai bank account for 2 months to be able to apply for the “1-year Extension of Stay Permit” on Immigration
for the financial proof for an extension of stay permit based on being married to a Thai wife, consecutive monthly transfers of a minimum of 40,000 THB equivalent need to be coming from abroad month for month not missing out one single month. Unless you have a work permit and earn income inside Thailand
