Birth, marriage, adoption and kinship certificates should show the relationship chain clearly. Non-Chinese documents may need a readable translation when the reviewing office cannot evaluate them directly.
When family eligibility depends on adoption, the application should include the legal adoption record and identity documents that connect the adopted child, adoptive parents and inviter.
A traveler visiting a friend normally applies under the tourism category rather than Q or S family categories. If an invitation is used, it should identify the host and planned visit clearly.
Trade-fair visitors should document the commercial purpose with registration, invitation or Chinese trade-partner records and keep the event dates aligned with COVA.
Paid performance is not ordinary business travel. Performers should coordinate the competent cultural approval and work-authorization documents before applying for the appropriate work visa.
F visas cover qualifying non-commercial exchanges, visits, study tours and similar activities. The invitation should make clear that the activity is exchange rather than employment.
S2 can cover certain short private matters, but the applicant must document the real purpose. Medical cases should include provider, appointment and funding information.
A mainland Chinese visa does not by itself determine permission to enter Hong Kong. Hong Kong applies a separate immigration system based on nationality, purpose and length of stay.
Macao and mainland China operate separate immigration controls. A mainland visa is not a Macao visa, and returning from Macao may require another valid mainland entry.
An itinerary that enters China, visits Hong Kong, Macao or another country, and returns to mainland China may require multiple entries even when it is one vacation.
