Work in Myanmar for foreigners is hard to come by. NGOs and other aid groups operate in the capital and remote rural areas but may require specific skill sets to hire you. Another option is European and Asian companies, mostly operating on a small scale. Teaching English is feasible in private schools but many foreigners have reported unreasonable contracts, such as withholding pay and refusing to pay those who resign early. Skip entirely the education ministry, which only hires citizens with teaching certification. If you would like to work and assist Burmese refugees certain NGOs (http://www.akhathai.org) work in neighbouring Thailand
