Nonimmigrant visa applicants may now schedule interview appointments at any U.S. Consular Section in China, regardless of the province or city where they live. Consular Sections are located at the U.S. Embassy in Beijing and U.S. Consulates General in Chengdu, Guangzhou, Shanghai, and Shenyang. The U.S. Embassy in Beijing noted that, although the basic application process is the same, specific times and application procedures at each visa issuing office may vary. Before applying for a visa, applicants should check each post’s web site for procedures specific to that post.
