What is a F visa for China?
The China F category visa, namely the non-commercial visit visa, is issued to foreigners who are invited to conduct a lecture, an investigation, scientific and cultural exchanges, study tours, attend a conference or trade show, and other non-business activities in China.
The F category visa may also be issued, at the discretion of the Consulate, based upon the principal activity of your USA company.
It is normally issued for one entry valid for 3 months from the date of issue.
There is no 10 year validity F category visa.
