If you want to apply for a large credit card or gold card, it is recommended to provide more financial information. It can be a payroll record issued by a bank, an income tax withholding certificate, or a market value certificate of a house, a car, a deposit and an investment (such as a copy of a real estate license/car driving license/bank time deposit certificate) and other materials that can prove your economic level. Other documents for reference include: personal account list of social insurance in the last 6 months, water, electricity and gas bills, credit card bills of other banks, etc. Mainly a copy of your certificate of deposit, real estate license and driving license of high-end private car. If you can provide relatively complete financial documents, it will be more helpful for us to understand your personal situation and judge the credit limit. Where there are clear provisions in the local branch, the provisions of the local branch shall prevail, and the issuance of credit cards shall be subject to the final audit results.
