You can't get a credit card according to your own conditions. At present, the state has restricted college students from applying for credit cards, and it is also impossible to approve adult education and self-taught exams. . . There is no source of income. This is impossible to do.

Suggestion: See if you can get the income certificate of the unit. . . Some units are loosely managed. If you have acquaintances, I can give you an income certificate. . . . . General units can buy social security for half a year. It is better to deal with units. The examination and approval of the four major state-owned banks, China, agriculture, industry and construction, is relatively strict. I suggest you go to joint-stock commercial banks such as Xingye, China Merchants and Shanghai Pudong Development Bank.

If it is really not possible, do it in the name of parents or relatives. . (Of course, they should sign it themselves. )

The overdraft limit depends on your repayment ability. Generally speaking, the credit line of joint-stock commercial banks such as China Merchants and Xingye will be higher than that of state-owned banks. . It's just that it's inconvenient to have fewer business outlets.
