You are creating fear mongering in situations where people want practical advice. And u are also exaggerating the risk based on intuition rather than reported data.
And using a company who babysit you at the border is not a "misuse of visa rules?, lol! Naive guy. Which rule btw? There are no rules regarding the quantity of visas.
Wait .. what!? Border bounce = land entry. You won't get denied after 9 months, lol. Been here 12 years and still did a bounce last month, easy, just avoid Poipet
Enter by LAND only, do not fly in to BKK airport on visa exempt entry u have a high chance of getting denied entry. Avoid Poipet. Enter from Chong Chom (O'Smach). It's a very chill border.
Oh okay, It use to be easy to go to Perth to get METV for most nationalities. A lot of people I know were doing it. I don't know why it was possible but not anywhere else except your country of origin.
You do you John. I'm just saying to be careful because I personally know people like you that are now stuck in Cambodia and were speaking the way you just did. The crackdown last year was massive. Considering this is "online class" and your Thai is just "decent", these are two things that to me raise at least a yellow flag. And also your 4th year studying Thai which is unusual.
