回複：父母剛拿綠卡就申請政府補助的健康保險， 作為擔保人可能有多大幾率惹上法律官司？？謝。

I do not think you (擔保人) will have aproblem in this issue. If your parents are qualified for the insurance, the insurance company will approve their applications. If they are not qualified, the company will reject or deny their applications. Nothing complicated.
