Can I lend my credit card to my parents to go to America?
Yes, as long as you bring your visa and JBC, that's fine. It is recommended to get a MATTERCARD or VISA card before going abroad, which will be more useful. Be sure to check your signature, or you can swipe your card at the store designated by UnionPay, so you can do it in the way of swiping your card in China. I hope my answer can help you.
