No need to buy a plane ticket, book a bus to loas from Udon Thani

Ask at the immigration office

My immigration office is also Pathum Thani.. I can only info you of my dealings with Pathum Thani.

4 year's ago I wanted to change from O imm retirement visa to married visa.

Can not was the reply from immigration, they told me I had to leave Thailand and have my retirement O imm canceled then re-enter and apply for a new O imm based on married.

So I booked a flight to loas and came in on a 30 tourist visa.

The is a list of the Documents I needed visa based on Marriage

When I done my last extension on day 30 I had to phone immigration to see if they had the extension ok from Bangkok... took 45 days in total that was Pathum Thani immigration.

Thai visa service. Google is your friend. From Bangkok few times a week, very reliable and professional company

If you are planning to live here I would get a single non O and extended for 12 months, better than leaving ever 90 days which is a pain in the ass plus expensive

My local office at Pathum Thani immigration only want to see the bank book at the time when applying for the extension. When I return after 30 day's to get my final stamp no bank book is need... different immigration offices different rules.

I'm guessing you will need 800k EACH in a Thai bank account in your own name's
