thank you again. So, it seems like I could buy the re-entry permit more than once if needed, based on the validity you described.
To clarify, is time slot needed to apply for the 12 month extension 3-4 weeks towards the end of your non-0 90-days? And that is when you would receive a home visit if one happens? We may choose not to stay in Bangkok so I'll have to figure that out also.
Bank account:
no agent, no COR, no insurance purchase. I went in with my wife who has an account there and who needed to change her phone number in person in order to use their app, (a very tedious process as well). While we were there I asked what was needed to open an account and explained that I needed to open a bank account to deposit 400k to convert to a non-O visa. He requested, original marriage certificate, and the other marriage document K2 K3?, her ID, copy of tabian ban, My passport and another form of ID- (used my US driver license, and a copy of our signed lease. He wanted a 12 month lease, but was satisfied with a month long lease that had wording in it that it was extendable aka month-to-month. He also said that you need to have more than 30 days validity left on your permission stamp. Now that we are getting 60 days VE, it is easy to meet that condition.
No mention of Certificate of residence. No mention of additional letter from the embassy. When I asked about opening an account when we were visiting in 2022, they said a letter was needed and showed me a copy of one. I think it was just an document saying that you are who you say you are.
Went back the next day with requested documents, went straight to his desk and didn't have to queue, and took care of in less than an hour. I would expect people to have to wait quite a while there in general though. I overheard some officers saying that there are many people from Taiwan and Myanmar opening accounts to purchase property at this time.
