The most important condition for applying for a credit card is that you are at least 18-60 years old and have a stable job and income. 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 banks to understand your personal situation and judge the credit limit.
For example, if you have no job and are a private individual, you can provide your individual business license and tax bill for the last three months, and you can also provide other financial certificates, such as: proof of income tax withholding; Copy of self-owned real estate license; Copy of self-owned car driving license; Bank certificates of deposit and other information that can prove your economic level.
