The U.S. Mission China announced on December 15, 2022, that due to operational impacts caused by the surge of COVID-19 infections across China, all routine visa services at the U.S. embassy and consulates in China are temporarily suspended.
Specifically:
U.S. Embassy Beijing and U.S. Consulate General Shanghai are providing passport and emergency citizen services only.
U.S. Consulates General Wuhan, Shenyang, and Guangzhou will only be providing emergency consular services until further notice.
The announcement stated that some visa appointments previously scheduled at U.S. Consulate General Shanghai will be preserved, but all other nonimmigrant visa and immigrant visa appointments at the embassy and consulates in China have been canceled. Applicants will be contacted if their visa appointment is impacted.
Per Mission China, they are advising nonimmigrant visa applicants to reschedule their appointments for a later date by following the instructions at https://www.ustraveldocs.com/cn/cn-niv-visaapply.asp. Immigrant visa applicants with questions are advised to contact the IV unit through its online form found here: https://china.usembassy-china.org.cn/visas/immigrant-visas/immigrant-visa-unit-question/.
There is no indication of when visa services will resume.
