This is not entirely true. Malaysia and other countries have very conservative laws and social policies. Also, the English teaching industry is not what it was in the early 2000s. Most countries now have enough of their own English speaking population, and the.standards for foreign teachers have increased as a result. Even Vietnam requires a TESL diploma, which requires a degree to take. Any school that would employ someone illegally is not an employer to seek out as they (unsurprisingly) do illegal things in their workplace. Risk of deportation, the school being shut down, not getting paid, etc, is very high. Do not work illegally in another country.

I dont have any qualifications to teach.
