On the one hand, it depends on whether you have a job.

Another more important aspect is to calculate your income according to your social security payment (of course, it can't be very accurate, but usually people with high incomes pay more social security), so as to decide how much credit line to give you.

As we all know, in theory, the difficulty of credit card is determined by the nature of credit card overdraft first and then repayment, so banks value the applicant's economic strength most and are afraid of their own risks. Coupled with the current financial crisis, the era of banks expanding credit card territory at all costs has temporarily come to an end, and it will be very troublesome to follow the procedures stipulated by banks. Having said that, as long as the rules of the game aimed at making money remain unchanged, banks will continue to compete for the cake of credit cards after a period of time. In order to eat an extra piece of credit card cake, the bank has found many agents (individuals) to help promote it, and both sides can benefit. If you apply for a card in the street, or there is an enthusiastic person in the company to help you, you just need to give him a copy of your ID card, write your contact number on the application materials, sign your name, and then wait for the card.
