hello, if you apply for a CMB credit card, the most important condition is to have a stable job and income, and the necessary application documents are a copy of your identity certificate and work certificate. If you can provide other financial documents, it will be more helpful for us to understand your personal situation and judge the credit limit. The credit card application is comprehensively evaluated by the system, during which we refer to many factors, such as age, job stability, income, personal credit and so on. Perhaps your original application materials failed to fully show your real situation, which led to the failure of your application. If your work or financial information changes in the future, you can re-apply for the information after 3 months. I hope you can apply for the card next time!
