I reserved the credit card of China Merchants Bank online. Someone came to the door today. During the processing, I can ask my social security card number. Do I need a social security card?
None of the above answers are accurate. Accurately speaking, it is to prove your work income, but you don't need a social security account, you can find it with your ID card. Social security is to prove that you have a stable job. Stability is more important. Many social security payments are the lowest. The salary on social security is not necessarily related to the income you fill in the form.
