Went to Nonthaburi Immigration office yesterday to apply for first one year extension to non o retirement visa, apply for multiple re-entry permit and file first 90 day report. Whole process took 90 minutes.
Couple of things (maybe Nonthaburi specific);
1. Booked appointment online. Print out the booking confirmation and bring with you as they will ask for it.
2. Each page of your back up documentation ( passport pages, bank statements etc) need to be signed and certified “true copy”.
3. The STM.2 document that I had filled in beforehand was not accepted as there is a newer version. (It’s a simple document to fill in on the spot anyhow).
4. As I was there in person and applying for a one year extension, they didn’t even look at my 90 day report application. Note the next 90 day report is required 90 days after my visit to immigration ie March 22nd 2022 and NOT 90 days after start of my new visa extension.
