To apply for a credit card, you need to submit an application form and some personal data (identification and financial proof, etc.). If you have a copy of the real estate license or driver's license and a copy of the bank deposit slip/passbook, it may help to increase your credit limit. Among them, the materials that must be provided are: copy of ID card, income certificate/work certificate. Some banks may also require that professional title certificates, real estate licenses and other materials must be provided. If the company can organize a group to handle the card, the conditions may be relaxed. Generally, in addition to a copy of the ID card, only a copy of the work permit/certificate is required. The application form can be collected at each bank's business outlets, downloaded from the bank's credit card website, or called its customer service number. Fill in the application form and send it to the credit card center together with identification and work certificate. Generally, after 7 ~ 10 working days, you can check the application progress on the website or on the phone.
