Thailand visa for 90 days

Let's just say that if you can leave Thailand without being found out within 90 days, everything will be fine, but if you need to apply for a visa at the immigration office, they will turn over your 90 days first, and there will be nowhere to escape. My friend was fined 2000 baht. I wonder if he will be fined 5000 baht.

If it is really inconvenient for you to go to the immigration office in 90 days, then you can leave Thailand from other ports at your convenience (just go to Myanmar or Laos). If it really exceeds 90 days, you can also try to go out from these ports. Their management is not as strict as Bangkok. Because the calculation of 90 days is based on the date of your entry, if you leave the country in less than 90 days, they can't control it. As for the airport in Bangkok, sometimes it is checked and sometimes it is not. It depends on their mood. It's hard to say.
