Applicants must be physically in the United States when applying through a Chinese mission in the U.S.; preparing a draft abroad is not the same as submitting it.
A girlfriend, boyfriend or fiancé is not included in the published Q-visa family-member list solely because of that relationship; tourism normally points to an L visa.
One COVA account may be used for multiple family members, but every adult and child still needs a separate application with the correct filer declaration.
The public U.S. guide says to submit after the status appears but does not publish one universal 30-day clock; follow the dated reminder inside your own COVA order.
The current U.S. L-visa checklist does not list a financial bank statement as a standard tourist document, although a bank bill may be used as proof of residence.
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.
