谢谢各位大侠。 我想给我姐姐申请绿卡，她人在国内。
-She may have trouble to get the B2 visa due to immigration intent due to I-130 filing.
还有一问， 我的一个朋友的母亲告诉我说，她拿到绿卡后，直接给儿子半了绿卡， 这可能吗？
-Yes, but it may take several years for the son to get the immigration visa because the priority date takes long time to be current for F2A or F2B.
