It was mentioned in the Swift Student Challenge that outstanding winners will have the opportunity to visit Apple Park in the United States. However, as a challenger from China who is not currently in the U.S., this means that if I receive the outstanding award, I will need to apply for a visa to travel to Apple Park. Since I am under 18, my guardian would also need to apply for a visa. Therefore, I would like to know if Apple provides visa assistance for outstanding winners and their guardians from China, or if we are responsible for applying for the visas on our own.
Winner's visa issue
I can't talk from experience here, and I obviously cannot give you an official response, but you're likely not the first person from China, neither the first one who needs to apply for a visa, if this helps! :)
I'm pretty sure I saw a video with last years' distinguished winners, and I'm quite sure there was a student from China as well.
If you don't receive a response here, maybe you can contact the Swift Student Challenge team at swifstudentchallenge@apple.com
(from their T&C).
