Samut Songkhram.
Wife went to their office. She said they stated they would start visiting every year. She asks why. Response was some foreigners lie about where they live. Basically, calling me a liar.
On my 10th extension, I was in and out in 10 minutes. There were two people in the office. They looked at my record online. Saw that I had no lates on 90 day and no lates on annual extensions in 10 years. Briefly looked at the paperwork I submitted. Approved and out the door in 10 minutes. That is the only time that it happened like that.
As far as income verification, this office wants a copy of my U.S. bank transactions for the year. They want to see the source of the money going into my U.S. bank. Then they want to see the Wise transactions transferring the money to Thailand matched up to the deposits in my Thai bank. Also want an updated bank book and a bank letter of certification. They also want either 1099's or a certification of income for each income source. This is what I have been doing since the income letter was done away with. As you said, Thai bank statement should suffice. Seems like they want to make it as hard as they can.
The employees are fine with money in bank. When it comes to income, they have not received sufficient training.
Now I have to do four 90-day reporting's, annual extension, and a home visit every year.
