Crossing from Hong Kong to mainland China for US citizens
Important: US citizens are not covered by China's 30-day unilateral visa-free policy. A tourist L visa is required before crossing from Hong Kong into mainland China. Apply via cova.mfa.gov.cn.
US citizens can cross from Hong Kong into mainland China, but a tourist L visa is required in advance. Separate entry rules apply — Hong Kong admission does not grant access to mainland China.
| Detail | Information |
|---|---|
| Hong Kong to mainland China | Separate entry required |
| China visa for US citizens | Required — tourist L visa (US not covered by visa-free policy) |
| Re-entry to Hong Kong | Yes, new 90-day period begins |

Note: Hong Kong and mainland China are completely separate immigration destinations. Entering mainland China from Hong Kong requires meeting China's entry requirements independently.

Entry rules when crossing into mainland China
Tourist L visa required for US citizens
US citizens must obtain a tourist L visa before crossing from Hong Kong into mainland China. Apply online at cova.mfa.gov.cn, then submit your passport at a Chinese embassy, consulate, or CVASC. Processing typically takes 4–8 business days. Fees start at $140 at the consulate.
What resets when you cross
Time spent in Hong Kong does not count toward your China visa stay limit. When you return to Hong Kong from mainland China, a fresh 90-day Hong Kong admission begins.
Passport validity difference
Hong Kong requires your US passport to be valid for at least 1 month beyond your stay. Mainland China requires at least 6 months of validity beyond your entry date. If your passport has less than 6 months remaining, you can enter Hong Kong but will be denied entry into mainland China.
