In Chiang Mai I was told that, after transferring retirement visa stamps to new passport, I could go around the corner to the 90-day drive-thru window to do that operation and have my new passport number recorded. Just this week I tried doing the 90-day report online, and it was rejected. So having sent a new report by EMS, I am waiting for the receipt from Immigration, but the 4-day holiday is delaying a response.
