If it is a China Merchants Bank credit card, and the card has been repaid on time every issue and has no bad records, you can try to apply for a second one. If you already have our main credit card and want to change to another card type (you can Apply for multiple cards), it is recommended that you apply online or refill the application form (no other fees will be incurred except the annual fee), and the card number will be changed at that time (the original card can continue to be used before it expires). There is no need to provide proof of employment and identity documents again when applying. It usually takes 5 working days to check the application progress.
