Proof of residence (if you live in a residential area, let the property stamp you, if you live at home, let the neighborhood Committee stamp you). Then nothing happened. Wait for the call! It takes about 20 days from the time the bank sends your application to the time the bank informs you. If you are not informed within 20 days, you will be rejected.
You can apply to several banks at the same time, so there will always be one for you to approve. If more than one batch is approved for you at the same time, you can choose which one to use, and don't activate it if you don't use it.
If you have a job and your social security number can be found online, then you can 100% apply successfully. You can also choose a bank selectively. Generally speaking, the credit cards of Bank of Communications, Bank of China and Shenzhen Development Bank are the best. China Merchants Bank's credit card is recognized as the best, but it is also difficult to approve, just like state-owned banks.
Finally, there is another application, which is to apply for a card: that is to say, you already have a credit card and have used it for more than half a year, so you don't need any information, just need an ID card to handle it directly for you.
