Seeking entry-level employment in Singapore/ Hong Kong/ China

[000641133]

I'm a Malaysian citizen who will be graduating from a university in the US in December 2009.

I'm currently seeking entry-level employment in the following countries: Singapore, Hong Kong, mainland China (preferred in that order). I am proficient in Cantonese and Mandarin. I have three exams passed and I've recently sat for my fourth.

What's the best way to apply and get myself in? Also, will there be any immigration issues? Thanks a lot for the help!
