Suvarnabhumi Airport you would have been denied entry. FYI, the nightmare at
Suvarnabhumi Airport didn't start with Covid, it started in 2015. There was insane enforcement of no more than 6 months per year in Thailand that was getting more and more enforced, and then Covid hit. I avoided that airport for the last 5 years. Always entering via Chiang Mai or South Thailand, never had a problem. With Covid, most flights into Thailand were layover in Bangkok first, so people recently on Volunteer visas were fucked while trying to enter via BKK. But Phuket always does things first, Sandbox, etc, so there is direct flight to Phuket. Chiang Mai is lagging behind (every flight stops in Bangkok first).
Went did you enter the last time? (month) Which airport? How was your volunteer visa acquired? (agent or no agent), etc. I said impossible given OP situation.
Exactly, but some farang have been there a lot longer than others, and have been in way more situations than others, and have way more connections than others, and understand the Thai system way more then others.
. Most agents will sadly not deliver, or deliver sometimes. I have not step foot inside an immigration office for nearly 6 years, so I can tell you that not everything is sad story. Are you on overstay? You need to physically go there and get your passport back today.
Maybe, but until borders and the country fully re-open, we won't know. Things could very easily go in both directions (less strict or more strict). Also, BKK airport has always been way more strict than any other Thai airport in such regard. When Chiang Mai has direct flight again we will have more answers.
This is true, but... they are never actively looking at your full history. The same apply when people 3-4 years ago were going to Savannakhet (Laos) for a tourist visa. If you already had 2 consecutive tourists visa in Savannakhet, the 3rd one would be denied, unless you were on a new passport. It's been like this forever, a new passport is kinda golden. Ofc things could change at any moment.
A tourist visa received in your home country holds the same value as one done in Cambodia. If you want to enter again, go to your Embassy in Cambodia and make a new passport which will be empty of all stamps. Then apply for a tourist visa and try to get back into Thailand via Phuket. This plan is your best bet to get in, but not guaranteed.
