thanks Tod. Good to know. I am on my 5th year extension of a retirement (non O A) Visa which is definitely cheaper here than getting a new one in LA! Still dealing with dates. My return is the fly in the ointment as its business in the US.
Thank you for the prompt responses. Had hoped for different answer. Oh well, new Visa before I leave US. Timing doesnt work out for renewal in Thailand. Headed back to US for several months.
middle of the week is better than Monday or Friday. As is middle of the month. The offices give out limited numbers each day. People arrive early to ensure they get a number. Without a number you will probably not be able to do an extension. You should be fine.
Are you in a degree program at CMU or just taking Thai. If you are in a degree program that's a whole different animal from the schools who teach Thai as a way to stay in the country. The whole ORIGINAL point of the Ed Visa was to attract international students to Thai universities and colleges. Not so people could come and perpetually extend visas.
Assuming you are in a degre program (BA, MA, PhD ) the people at CMU are well aware of the visa regulations and requirements.
