Arriving first week of October - landing in Bangkok and then taking a connecting flight to Chiang Mai - with a narrow window of just 2 hours.
Should I get my visa stamped at Suvarnabhumi Airport or at Chiang Mai Airport?
Thank you for your help :)
TLDR : Answer Summary
When arriving in Bangkok and transferring to a connecting flight to Chiang Mai, you should get your visa stamped at Suvarnabhumi Airport (BKK). Although you have a narrow window of two hours, if your baggage is checked through to Chiang Mai, this time is generally considered sufficient. You will need to pass through immigration at BKK before boarding your domestic flight to CNX. It's advisable to account for potential queues at immigration, especially during busy times.
