多年前给弟弟一家办移民，主要担心侄子考不上大学留条路。最近收到“Notice of Immigrant Visa Case Creation", 可是侄子已经快21岁 （到10月底21岁），考上了大学还有一年就毕业了，弟弟弟妹没有退休，辞职过来意义已经不大了，就想放弃移民。
-You may just calculate the child's CSPA age to see whether the child will be age-out. If no, the child may immigrate to US together with the parent.
The child's CSPA age = the child's actual age when the I-130 priority date is current (排期到时）- the I-130 pending days
Note: I-130 pending days = I-130 approval date (i.e. approval notice issued date) - I-130 receipt date
You can find these two kinds of dates on the I-130 approval notice.
If the child's CSPA age is less than 21, then the child is not age-out and thus, he can immigrate to US witt the parents.
请问在这种情况下如何退出，
-You just need to write a letter to USCIS to withdraw the approved I-130 (provide the copy of I-130 approval notice). That is all.
他们以后还想来美国旅游的，希望不影响正常的旅游签证。我什么都不懂，先谢谢各位老师了！！
