請問
我姨媽給我母親十幾年前申請了親屬移民但是一直沒排上，現在我可以給我母親申請移民嗎？-Yes if you are a US citizedn. 沒有什麽影響吧？-Not affect anything.
父母離異，給他們申請綠卡的時候需要結婚證離婚證都遞交嗎？-Yes.
境內申請綠卡也需要提交無犯罪記錄公證嗎？-Not need it if they file I-485 in US.
父母有了綠卡後可以立即回國嗎？-Yes, but had better not stay outside US for > 6 months. 如果不急著入籍，最多在境外不能超過多久？-If they are not used to living in US permanently, they had better not get the green card. I have seen many Chinese's parents abandoned their green card because they were not used to living in US.
有綠卡父母，但沒有美國收入，必須報稅和有醫療保險嗎？-If their income is lower than the threshold for IRS tax filing, they don't need to file the tax return, but they had better have health insurance.
不好意思給您這麽多問題，非常非常感謝！
