Chinese regulations provide that applications for residence permits valid for more than one year generally require a health certificate, subject to the local authority's process.
A visa invitation should be complete, signed where required and readable. Published requirements generally accept a fax, photocopy or printout but may request the original.
A business invitation should identify the Chinese trade partner, applicant, commercial purpose, dates and who bears expenses, with credible company contact details.
The inviter's proof depends on status: a Chinese citizen generally supplies a Chinese ID, while a foreign permanent resident supplies passport and Chinese permanent-residence documentation.
For an S family visit, the host in China is a foreigner working or studying there. The file should connect that host's current passport and residence status to the applicant.
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.
