Visa-free transit for Z100?
I am looking at the following itinerary:
- Day 1: Arrive in Beijing from US 17:00 (SFO-PEK)
- Day 4: Fly from Beijing to Hong Kong 20:00 (PEK-HKG)
- Day 6: Depart via train from Hong Kong to Shanghai 15:15 (Z100)
- Day 10: Depart from Shanghai for US 08:30 (SHA-PEK-SFO)
I've read your excellent "144-Hour Free Transit" page which suggests that a Shanghai arrival via train and departure via airport qualifies for free transit because of Shanghai's more flexible list of more eligible transit ports.
Have I read this correctly? My plan is to use the 72-hour free transit policy in Beijing, and the 144-hour free transit policy in Shanghai, since I am arriving and departing from outside countries/regions. However, I am not clear about two things:
- Will I be permitted to board the Z100 train in Kowloon without an entry permit?
- Will I have problems on the train without an entry permit, since it stops in several cities before arriving in Shanghai?
