Apply for a position of interpretation

I suggest your failure to use the appropriate noun "interpreter" in your request "shoots you in the foot".

Yeah, I have noticed the mistake after typing and failed to correct it. Now I post a new one. Thanks for your suggestion.

Where are you now? In China or the USA? If you're an American citizen or here on a legal work visa, your best bet is to contact the Office of Language Services at the US State Department. They employ a large corps of interpreters on a contract basis in virtually every language spoken on this planet. It's not steady work (you get paid only for the time you actually work under contract)but it's quite competitively remunerative

Thanks for your detailed information, but I am now in Beijing!

You could, of course, contact the American Embassy in Beijing and ask whether they ever have need for an English-language interpreter in China. Do the same with the British, the Canadians, Australians and New Zealanders. You never know what might turn up unless you ask.

Yeah, I have applied for jobs relevant to English by filling the application form provided by these embassies, but no response. Perhaps it is because that I just graduated.
