Aliens should apply from the Chinese embassy, consulate, or Chinese Visa Application Service Center (CVASC), which is in charge of their residence area. For example, if you live in Colorado, you should submit an application to the Chinese Consulate in Chicago. You must apply to the embassy that serves the state, which is your legal residence (i.e., the state listed on your driver’s license). The Chinese embassy in the US is located at 2201 Wisconsin Avenue NW, Suite110, Washington, D.C. 20007 U.S.A. You can contact them via email at washington_visa@csm.mfa.gov.cn or by phone at 001-202-855-1555.
Though requirements do vary depending on the visa the applicant needs to enter Mainland China, most foreign nationals who wish to obtain a Chinese visa will need the following: a passport, a recent photo, a China visa application form, and proof of residency. Passports with over 6 months validity, completed visa application forms, qualified photos, and supporting documents like air tickets and hotel reservations, invitation letters, etc., are also required. You can visit the website “China Online Visa Application (COVA)” to fill in the COVA forms and make appointments for on-site submission at the Visa Office through the website “Appointment for Visa Application Submission (AVAS).”
