As long as you are 18 years old and have a regular job, you can apply for a credit card. Social security is just one of the materials that banks need to review. The bank will use this system to approve individual comprehensive scores. Banks have different standards for individual comprehensive scores, so the approval results will be different. But social security alone is not enough. You need to prepare other materials to support it. Generally speaking, there are:

1. The work certificate issued by the work unit can also be a copy of your work permit.

2. If you have a house in this city, you can submit a real estate license. If it is a rental house, a rental contract can be provided.

If there is a private car under the landlord's name, you can submit a copy of the motor vehicle driving license.

4. There are also proof of payment of social security and five insurances and one gold in the past three months.

5. Other proof of capital contribution can be submitted.

If the above materials are provided, the chances of success are high and the quota will be higher. If you are not satisfied with the quota in the end, you can raise it for half a year first, and then apply to the bank for an increase. Generally, the increase is 50% of the existing quota. I hope my answer can help the landlord!
