Social Security and said that I did not pay SSN tax and it would affect the social security credit.
I am currently employed and I do pay social security tax. I remember that I did not pay SSN tax when I was F1 student before, I worked as a Graduate Research Assistant when I was a F1 student before.

I am confused.
