If you have a real estate certificate or property certificate, such as a driver's license and a copy of the bank deposit slip/passbook, it will be helpful to increase the credit limit when applying for a credit card. If your annual income is 50,000, the credit card limit will be around 5,000 to 6,000. If you want the limit to be higher, it will be automatically increased based on your consumption, usually within three months. In addition, you can also apply for a temporary limit increase (I don’t know if CITIC has this service, the CCB card I used has it). The above is my answer to your question. I wonder if it can help you. If so, I hope you will adopt it!
