Can I apply for a Retirement Visa or Non-Immigrant O in Thailand without proving residence?

Hi together, I where yesterday in Phayao.

They said to me I should to go go to Lampang where I have to go. Otherwise I can pay 40.000 Bath for the Same Visa Service like in Chiang Mai.

Your original question about having no established residence... It is easier than you may think. Live where you want to ... but in the same area you can do something like striking up a relationship with a Guesthouse owner/manager - book a room whether you stay or not... In this process get a receipt for your stay. You may try to see if the Manager will write a receipt for a longer term - for a modest inducement. Nothing states that you have to live in a Condo, leased Bungalow or Apartment. A Guesthouse or modest hotel will do nicely.

Just a correction.

You can ONLY get a Non-Immigrant Type O-A (Long Stay) visa in your country. That's the one that takes a police background check, a medical certificate and proof of adequate funds.

You can get a Non-O visa because you're over 50 (retirement) inside the country at the immigration office or at a thai consulate in a near by country by meeting the financial requirements.

Going to Vientiane, Laos to apply for a Non Immigrant O Visa 90 days at the Thai Embassy there would be a good first step. Then upon returning to Thailand you apply for the Extension of Stay based on being over age 50 / Retirement at the local Immigration office. You will need proof of meeting financial requirements for both the initial O visa and the Extension but they are both the same. For a lot of people the simplest method in proving income from outside Thailand of the Equivalent of 65,000 Baht a month. You can get an official form letter - Income Letter / Affidavit at your own Embassy in Bkk. Proof of income to the Embassy depends on the policy of your Embassy. It all sounds a bit foreboding but taken step by step it is not all that difficult

IF your immigration office can do it, and you don't have enough time on this 30 day visa exempt stamp you can apply for a 30 day extension for 1900baht and then apply for the 90 day Non-O

There is a way to get an in country 90 day Non-O at the immigration office but you'd need at least 15 days left on your current admitted until" stamp. If you meet the financial requirements go to the immigration office and ask what the procedure is up there. It's 2000baht to go from a 30 day visa exempt or a tourist visa to a 90 day Non-O inside the country.

Failing that you could go to a thai consulate in a neighboring country and buy a single entry 90 day Non-O and then apply for an extension based on being over 50 (retirement) after that at the immigration office.

To apply for Extension Of Stay at Immigration office in Thailand you need an address in Thailand.

Ok, you are too late to convert. You will need to go to an embassy,consulate get a new single entry Non-O and start the whole process again.
