There are TEFL certificatication schools that offer non-B visas. Some offer ED visas if you also take Thai language classes. When I did it, I got a 1 year multi-entry non-B from Houston by mail (LA is a little unfriendly). You probably can't get the 1 year anymore, but 3 months is enough to complete your TEFL, get a job with work permit and extension of stay. Get a certified diploma and transcript from your uni while you are in the states.
Also, if you forget photos, there's a dance shoe shop on the first floor of Pacific Place Shopping Centre (also linked by skywalk to Fairmont House) called Repetto (Shop 133, 1st floor) that does photos
Your passport and $50. An American notarization only certifies that the signatory proved his or her identity to the notary and that the notary was satisfied that the signatory understood the affidavit or document being signed. The truth of the contents of the affidavit is based on the oath contained in the affidavit to which the affiant affirms. The notary does not verify the accuracy or truth of the contents.
The worker documents are your CV, education degree and transcripts, employment release letters or verifications, a current medical certificate, passport with Non-B or Non-O visa, and photos. Your employer must provide company documents.
You need to apply for and obtain a Thai ID card, otherwise you will also need a work permit. The Thai passport doesn't confer citizenship rights and sometimes it is difficult for a foreign-born Thai to gain citizenship. A lot of it is dependent on your parents' domicile and land ownership.
Julian K. Glasser Don't worry about visa agents now. This group can give you all the advice you need. You can stay for almost a year without any help from agents and that should give you enough time to find an employer who will take care of your visa and work permit.
Julian K. Glasser You can only get a Non-O or Non-B visa if you have a Thai spouse or sponsoring employer. When I first came to Thailand, I signed up for a TEFL course that sponsored my 1 year multi-entry Non-B visa. That isn't an available route anymore. Best to just arrive on a visa exempt entry and sort things out as your options develop.
That's not good advice. First, agencies are mostly scams. You don't need an agency to get a teaching job. Second, they don't prosecute foreigners who are looking for work, or their employers are dealing with the work permit application process. Any employer worth working for can navigate the process. I've been hiring employees for 10 years in Thailand and never had an issue that couldn't be solved. I've gone through this process with hundreds of foreigners.
