Q: I am a Cambodian citizen residing in Japan and will transit through Shanghai Pudong International Airport on Oct 2. I hold a single-use Cambodian Temporary Travel Document that is valid until Dec 7. Can I transit without a Chinese visa, and would this qualify for the 24-hour visa-free transit policy?
A: Based on the itinerary you described (Japan-Shanghai-Cambodia), it qualifies for the 24-hour visa-free transit policy.
However, because your travel document has less than three months of validity remaining, you are not eligible to apply for a temporary entry permit.
Please confirm with your airline whether your booked flights are eligible for direct transit.
