The embassy provides a full suite of visa services, acting as a primary gateway for Chinese citizens traveling to the U.S. for education, business, and tourism. It processes a vast number of student visas (F-1), reflecting the large contingent of Chinese students in the U.S., alongside business visas (B-1) for trade and investment, and work visas (H, L, O) for specialized talent. The visa section's operations are a barometer of U.S.-China people-to-people exchanges.
