面试完快4个月了，还在等消息。我们订了感恩节去墨西哥，12月3号回来。需要给他们注册那个evus吗？他们有回美证，明年2月之前可以再用一次。像他们这样再次入境，人家是看签证还是看回美证呢？
-It seems they have filed I-485, right? If yes, they can not use the B-2 visa anymore, and have to use advance parole (AP) to travel to Mexico or China (show the AP to the IO when they re-enter US, not B-2 visa). Not need to enroll EVUS in this case.
