Hi everyone! I'm traveling from the USA -> Singapore -> Shanghai -> Singapore -> Japan -> USA. I am staying in Shanghai for 4 days to go to Shanghai Disneyland, and I am wondering if I need a visa for my short trip. And if I don't need a visa, and I have filled out the arrival form, is there any other information or documents I need to have printed/filled out and with me that might be required upon arrival? Thank you so much for the help!
