Everyone applies for a different credit card approval amount. The bank will give the corresponding credit card credit limit according to everyone's conditions and repayment ability. When you apply for a credit card again, you can provide more proof of property or enough information to prove your repayment ability, which will help to increase the credit card limit you apply for.
Every time you apply for a credit card or loan, the bank will check your personal credit. Credit records can not only accumulate your credit information, but also reflect whether you have enough repayment ability.
