Some ordinary passports, including France, Germany and British citizens, currently have a 30-day short-visit waiver. The published deadline for these passports is 31 December 2026: do not assume it covers a 2027 trip. The US is not on this unilateral waiver list.
Eligible travellers, including US citizens, may instead explore 240-hour transit permission: the country/region immediately before and after mainland China must differ, tickets and designated ports must qualify, and travel must remain within permitted areas. It is not a general 10-day tourist visa.
Chongqing Jiangbei International Airport is a designated entry port; Chongqing Municipality is a permitted stay area. Any onward domestic stops must also remain within the NIA's permitted areas.
