有朋友在這邊工作 收入很低，一年兩萬左右。工簽工作。如果申請醫療保險， 用了Medicare 或者是其它的優惠政策， 以後申請綠卡或者公民， 有沒有影響？謝謝！
-Unless you have worked in US for 40 quarters (i.e. 10 years), it may affect your future green card application if you use Medicare benefits. But if you use your employer's benefits, i.e. join the group health insurance your employer provide, or purchase private health insurance, that will be fine.
