有兩個疑惑：
1.我父親在過去的10年內累積滿了40個工作點數，一直是無身份狀態。目前我想用公民身份來給他申請綠卡。請問，如果拿到綠卡，是否可以享受到政府的社安金？
-I think so if he has paid the income tax and social security/medicare tax during the period of time.
2.如果拿到綠卡，他在大陸居住的話，是否可以拿到社安金？
-Yes as long as he keeps his green card valid (how to keep the green card valid is a problem for him).
