Wait, you're living here but you aren't a citizen, and you're earning money (from elsewhere or whatever, it doesn't matter) and you...what? Plan to keep living here? That about right? Sorry, you're eventually going to have to pay taxes somewhere along the line, either here or back in your home country.
I'd say you best contact someone at:

Unless you're here illegally, then I'd have to say don't contact them. :D
