Actually, for someone like you, I can suggest that you submit all your financial proof and get a card from a salesman. I think you can do it before October 1.
also, I advise you, even if it is not a gold card, it is useless for you to take it abroad. Snacks and drinks do not support credit card. Buying local handicrafts is not supported (the handling fee is too high). You can only shop in big shopping malls. Obviously, even if you are a dual-currency Puka, it is no use handling it, like a scarf in Britain, with local characteristics. It costs 25 euros in local shopping malls, but RMB is almost the same as 25 yuan. Don't talk about clothes. That is to say, our country's consumption is low after all, and the credit card limit is naturally low. Foreigners' credit cards are generally 5-2W euros.
