太感谢了，不胜感激，8老师。还有两个问题。
1）公司e-verify后， 我们需要重新提交OPT extension application吗还是由公司负责处理？我们想避免因为e-verify问题申请被拒。
2）看到下面的grace period, 如果被拒，我提交I130 for F2B, 是不是小孩需要离开美国？
If your application for a STEM OPT extension is denied during the 180 days, you will receive a 60-day grace period to prepare to depart the U.S., apply for a graduate program, or apply for an adjustment of status to a different nonimmigrant visa.
再次感谢！！
