You can apply for credit cards from different banks at the same time, and it takes 3 months or more for the same bank to apply repeatedly.

Information or certificates required for handling credit cards.

1. Domestic residents only need to provide: a completed and signed application form, identity certificate, residence certificate and income certificate;

2. Foreigners and Hong Kong, Macao and Taiwan people also need to provide: a foreigner's residence permit (the reason for residence must be employment) or a foreigner/Hong Kong, Macao and Taiwan people's employment permit;
