This information is only used for credit card review and will be kept confidential. After receiving your application materials, our credit card promoters will forward them to the audit department of the credit card center. It usually takes 10 working days from the receipt of your application materials by the audit department to the completion of the credit card audit. After approval, we will make a card for you within 2 working days, and then send it to you by registered mail according to the billing address. Generally, the sending time of registered letters is within 15 days. Please be patient. Taking pictures instead of copying is generally no problem. If the time is different, the person who handled it for you shall prevail. If it is fast, it will be ready in 7 days, usually half a month to 1 month. You can check the progress online. 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 and an investment (such as a copy of a real estate license/car driving license/bank time deposit certificate) and other materials that can prove your economic level.
