What is the likelihood of being denied re-entry at Mae Sai? I'm on a SETV at the moment, which I will extend for 30 days before doing a border run.
In the past 2 years, I've had 2 SETVs (extended) and 3 visa exemptions (2 air + 1 Mae Sai border run). I haven't been here constantly, I've left for periods of 4-6 months 3 times but I'm getting a bit worried that my passport is filling up with Thai visa's and entry stamps and I don't want to risk being stuck in Burma will all my stuff in Thailand.
