动手给父母准备绿卡申请有点晚，现在眼看已经延过一次的探亲签证就要过期，而国内的公证文件还迟迟没有办好。不想让父母黑掉，打算给父母办二次延期，请问有谁给父母办过第二次延期的？理由是什么呢？有好心人给个建议吗？谢谢！
-I don't think USCIS will approve their second B-2 status extension application. Also it is useless because you will sponosr their green card and their illegal stay will not affect their green card application.
