第一个问题：我们带小孩一起申请移民，如果递交申请时小孩未满21岁，但在绿卡的等待期，小孩年龄超过了21岁，是不是小孩应该可以获得绿卡？ 应该以申请递交时，小孩年龄满足条件为准？
-Depends. If the child's CSPA age is < 21 when the priority date is current, then the child is not age-out.
CSPA age = the child actual age when the priority date is current - I-130/I-140 pending dates
Note: I-130/I-140 pending dates = I-130/I-140 approval date - I-130/I-140 receipt date
both the dates can be found in the I-130/I-140 approval notice.
第二个问题，在移民申请的等待期，我们还能以旅游签证入境美国吗？-Depends how long the priority date will be current. If it still takes several years, then it should be fine to visit US using B1/B2 visa.
