You can prepare the online COVA stage while keeping your passport for another trip, but the original passport must be available once the application reaches the submission stage.
A dual citizen should use one consistent travel passport for COVA, visa issuance and entry, disclose nationality history truthfully, and resolve any possible Chinese-nationality issue first.
Choose Q2 when visiting a Chinese citizen or Chinese permanent resident, and S2 when visiting a qualifying foreign family member working or studying in China or for another private matter.
China does not use one published nationwide salary minimum for every foreign work-permit route, but salary affects points, eligibility evidence and later tax-record checks.
The work-permit notification is a China-side employer filing completed before the Z visa; its timing is separate from COVA, passport processing and the post-entry permit.
The current U.S. Z-visa list names the work-permit notification, while medical evidence belongs to the China-side work-permit and residence workflow and varies by local filing stage.
Current U.S. guidance requires a dated M invitation with specific trip and inviter details but does not publish one universal number of days before every invitation expires.
The X1 residence-permit deadline runs from entry into China, not the visa's issue date; students should coordinate registration and local steps before arriving too early.
Current U.S. guidance describes Q2 for relatives of Chinese citizens or Chinese permanent residents and requires relationship proof, without repeating Q1's enumerated family-member list.
China's work-permit points route can support Category B at 60 points or Category A at 85 points, but it is only one eligibility route and never an automatic approval.
