If you need to apply for another bank's credit card, you can only use the conventional method. The required supporting documents are:
1, identification: usually ID card;
2. Work certificate: it can be the original work certificate issued by the employer (please indicate the specific company name, department, position and income, and affix the official seal or personnel seal of the company), or it can be a copy of the work permit verified and marked by the sponsor;
3. Proof of financial resources: 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 or an investment (such as a copy of the real estate license/car driving license/bank time deposit certificate) and other materials that can prove your economic level.
There are three ways to apply for credit card recommendation: directly log in to the bank in official website and submit the application, go to the bank counter and contact the business personnel to handle it at home. I hope you can take my advice.
