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。

when your parents apply for medicaid, they must include the sponsor's income as the total income. Obviously, since you filed I-864, they are not eligible for medicaid. If your parents failed to include your income as their total income in the application and get medicaid, and this was discovered by government, legally the government can sue you.
