Hi! I am a mexican who has permanent resident card and i live in US.
i need to go to China for business purpose in 2 weeks. My questions are:
1.- What process i need to follow if i am living in US but i'm mexican?.
2.- I read in the website from houston china consulate that " Mailed applications are not acceptable and will be refused". I can't go to Houston for the visa, so, how would that work?.

thanks a lot for your help!
