Dad died 2009 when I took my my mom to start getting his social security that he was getting we were told she can’t get it because he was only getting subsidized social security. One of his employers didn’t pay full tax for him one year. We are not from America. My dad became a naturalized citizen, but Mom just has a green card. I need to know if there is anything I can do to get it or some assistance for her to get it?
