Probably won't happen. What many don't realise it's not an immigration office issue. It comes under MFA, which is a totally different ministry. The MFA generally makes announcements in a timely manner, as opposed to the Royal Thai Police, who make announcements at the last minute
If you're still within the dates on the ORIGINAL visa, you don't need a re-entry permit. You'll be stamped in for another year providing you also extend your insurance cover.
They are only getting strict with people who are trying to scam the system. Unfortunately this makes it harder on those of us with proper visas doing the right thing because everyone gets tarred with the same brush. I don't know why people just don't get proper visas which represent what they are doing in Thailand.
What he means is it's not a legitimate visa. You've been in the country for a year under false pretenses and reading your comments you've been well aware of this but are feigning innocence. Thai immigration cracked down on these fake visas and a lot of staff were sacked or moved. Your card is marked. Neighbouring countries embassies know about the scam, so little chance of getting a visa there, and now you're thinking of living in the country by way of successive border bounces. You have to realise that Thai Immigration takes a dim view of farangs taking the piss. Perhaps return to your own country, wait a while then try the METV route.
Ok do what you have to do. You've asked for advice which several people have given you, but you seem to already know what you want to do and must have plenty of spare cash to throw at an agent to do what the school will do anyway. Good luck. I hope you don't lose your money
