I've been in Thailand since yesterday with a non-O visa valid for 90 days. I rented an apartment for one year; I have a lease. The apartment building owner filled out the TM30 form online and forwarded it to the immigration office in Pathum Thani. I've already been to the immigration office twice today, but each time I was told to have the TM30 form filled out and brought with me, even though it had already been forwarded online. I was able to easily open a bank account with Kasikornbank, since I have my visa, my lease, and a Thai phone number. Everything was arranged within an hour. The bank opened an account for me, an ATM card, and a banking app. I've already deposited 900,000 baht via Wise. It took less than two seconds for it to appear in my Thai account. I think the woman at the immigration office got nervous because I've already been there twice today, so I wanted to ask for advice here. My question now is: What exactly do I need to apply for a one-year extension? When should I do that? The day before my 90-day period expires? Should I skip the TM 30 form now since I already have a bank account, and just wait until the day I return to immigration? Thank you in advance for the positive responses.
