How many years do I have to pay social security at the age of 20?

Hello! If you are too young to buy social security, you have to pay for it for many years. General social security needs to pay 15 years or more, and you can only retire after paying 15 years to 60 years old. In other words, the period from 15 years after you hand it in to 60 years old is an empty period and there is no guarantee. I suggest you buy a guaranteed commercial insurance now and consider social security later. You can contact me if you need anything.
