母亲去年12月2日来美,I94 6月1日到期,我在4月份网上申请延期6个月到12月1日,目前没有结果。我看了下机票,最早的合适机票是12月初,已经晚于12月1日。请问：
1.如果延期批准到12月1日,她晚几天离境有问题吗？-It will not affect her to apply for a visa and re-enter US in the future, but her current 10-year B 2 visa will be void, so she needs to apply for a new visa to come to US in the future.
2.如果延期被拒绝,但买不到机票,那我们应该怎么办？-Leave US within one month from the date it is denied.
3.现在是否应该给她申请绿卡,以防I94过期她仍走不了？因为即便买了机要,就怕冬天疫情加重航班取消。
-Up to her. If she wants to leave US permanently, just sponosr her green card any time even if after she illegal stays. Otherwise, she can file second extension application after the current pending application is approved, and then leave US before the second application approval or denial.
再次感谢。
