If the social security is not full after immigration, can I continue to pay it myself? If not, surrender before emigration

1, if you have retired before immigration, you can continue to receive pensions.

2, less than retirement age, need to be divided into two aspects. The first is to see if social security has been paid for fifteen years. After fifteen years, I will go through retirement procedures and enjoy pension benefits. If 15 years has not been paid, once the immigrants are naturalized, they cannot continue to pay social security in their personal capacity. In this case, you can only wait until you reach retirement age to take out your part, and the part paid by the company and the part coordinated by the state will not be taken out.
