To apply for a credit card in the United States, you need to have an SSN number, that is, a social security number, and then you can apply for a debit card at the bank with your valid certificate. Generally, applying for a credit card directly is likely to be rejected, because the bank depends on your credit history, and because you are a newcomer, the bank does not have your credit history to check. Anyway, if you open an account first, you will have a chance to accumulate credit. When you have enough credit limit, you can apply for a credit card. Or if you have opened a bank account with the issuing bank for 1.5 years (Chase Bank), you can also try to apply for a credit card. There is also a prepaid credit card in BOA- Bank of America, which is more suitable for newcomers to establish their own credit, that is, to pay a certain mortgage (several hundred to 65,438+0,000 US dollars) first. After receiving the money, the bank will use your money as your credit limit and issue you a credit card, so you can use this card to establish your credit record, but using this card will not increase your credit card limit. After you have used it for a while and have a good credit record, don't worry, credit card pre-approval letters from other banks will fly like snowflakes. At this time, you can apply for a regular credit card and cancel the prepaid credit card in Bao Er. Bao Er will refund you the money you paid in advance by cheque.
