Leave Country With Expired 90-Day Report?

[OliverKlozerof]

I mailed in my 90-day report, as usual, only this time it didn't come back approved in timely fashion. I have registered mail receipt. A month later I realized I still had "2018" on the form I printed, and that's probably why it didn't come back. I'm flying out of the country next month. I really don't want to go out to Chaeng Wattana for a day to deal with it. What, if anything, will happen to me at the airport with an expired 90-day report? If a fine, how much and how much delay can I expect? Thx.

Immigration on departure form the country do not look for 90 day report receipts and have no way to check if they have been done.

Take your out old receipt so it does not get in the way.
