The supporting documents to be provided are:
1. Income certificate and company certificate (you can ask the company to issue a certificate, so that the probability of passing the audit is higher);
2. identification: the identity card of the applicant who has reached the age of 18;
3. proof of financial resources: it can be payroll records issued by banks, or income tax withholding vouchers, or documents proving the market value of houses, cars, deposits and investments (such as a copy of real estate license/automobile driving license/bank time deposit certificate);
4. Other documents for reference include: personal account list of social insurance in recent 6 months, water and gas bills, credit card bills of other banks, etc.
According to the situation you described, you can only try to apply, and the chances of approving the card are not great. You need to submit proof of work and income, and fill in the information application. If there is no insurance, the bank will focus on reviewing your work information.
if you can provide proof of financial resources as much as possible, I wish you success in handling the card!
