Just a shout-out to Chiang Rai Immigration. They underwent a recent change of leadership and are now very straight-forward, albeit very particular about requirements and details. However, you will not be suggested an additional fee for services which is just a bribe undercover. I just did my annual renewal application and was in the waiting period for approval when my 90-day came due. I have always filed them online but it was rejected this time so I went in. My window for the 90-day ended less than a week before the date I was given for receiving my annual renewal stamp, so when I went in for the 90-day, I asked if the annual was maybe finished and sure enough it was, so I got the annual stamp, 90-day, and saved another one-hour drive to come in again. The immigration officer was very friendly and courteous (as they usually are in this office) and I went away a happy camper. Good job for RTP-Immigration Chiang Rai.
