Online 90 Day Report - Chiang Rai Immigration Office.
I have a Thai marriage visa "1-Year Extension of Stay Based on Marriage". Earlier this year I traveled out of Thailand and returned (using my Re-Entry Permit) and "Checked In" at my local police station because I live in a rural area. I did my first 90 day report in person ( because you have to report in person the first time) at the Chiang Rai Immigration Office with no issues. :)
I have just completed my first 'Online 90 Day Report"! It was simple and I received approval less than 48 hours later. I then was able to print out the exact "Receipt of Notification" (that includes the next reporting date) that the local office usually staple in my passport.
This was a painless exercise, saving me a trip and some time to the Chiang Rai Office.
I hope this info is helpful to those of you who don't like waiting. :)
