As long as you 18 years old, you can go to the bank to apply for a credit card. General banks require credit card applicants to be 18-60 years old.

However, if you just turned 18, your application for credit card approval is easily rejected because you have no repayment ability and qualification certificate.

When you apply for a credit card, you must read it carefully, don't blindly apply for it, and you must find a regular bank to apply for it. Some credit cards on the Internet often attract friends who have little experience in handling credit cards under the banner of "high quota" and "quick review". If you really apply, your personal information may be leaked, which will seriously affect your reputation.
