I ve been warning about Dave for years. Keep away from this profiteer and liar who is nothing but a con merchant with no morals or ethics.

Ignore any job offers on his site, whether in China, Thailand, Korea, etc.

You can get yourself in deep shit nowadays in any of these countries if you don't have the correct visa, or proper credentials.
In Thailand you can be thrown into an immigration detention centre for visa violations, especially for working illegally, not a nice place to be.

Take up jobs that say "no experience required", "tourist visa ok" or other crap like that, get caught, expect to be jailed, deported, or very heavily fined before you are allowed to leave the country.

If you have to work illegally in Asia don't go there!
