I've had the same problem with the Kalasin Office, I was also due on the ninth. EMS tracing shows they received my report on the 7th, I have not received notification yet. Fortunately I was able to get hold of Kalasin Immigration, and talked to a very nice lady who spoke very good English. She said the notification was in the mail and not to worry.
why don't you mail them in? A copy of the passports and a self addressed pre stamped envelope and the form filled out, is all that is needed. Mail it 7 to 14 days before they are due. If for some reason you don't get it back, you still have 7 days after due date to report.
I got a new passport in Canada, my last trip. I came into Thailand and showed them the old passport with the reentry permit, no problem entering. I then went to immigration and had everything transferred to my new passport.
I have a friend who had his ฿800,000 in a year deposit, every year he turned it over into a new one. One year he did it and the bank didn't express that in their letter. Because the new deposit was new, however a transfer from the old one, Immigration said it wasn't seeded long enough. So be very careful, and probably a trip to immigration to explain what you plan to do, and see if it would be okay, would be worth your while.
that was not the case at the Kalasin office, I didn't have to show my bank book. It would show nothing anyhow as I get my money from an ATM card from my Canadian Credit Union. What you describe would be a complete rewrite of the rules. When certain embassies stoped issuing income letters Immigration came up with showing a direct foreign monthly deposit into your Thai bank account so those who could no longer get the letter could show proof of income. It does not apply to those who can get the letter.
no go back to the site, it has three things you can click on. The one in the middle you click to see your status. Click that and at the bottom click and you will get your new reporting date.
