嫂嫂的亲戚10年前帮她申请了亲属移民，但没有帮我哥和我侄子同时申请， 现在我哥哥和我侄子（16岁）也想移民。请问可以在我嫂嫂原来的申请上加他们吗？
-Yes. The whole members can apply for the immigrant visa together when the priority date is current, but the kid's CSPA age must be less than 21 at that time.
Note: the child'CSPA age = the child's actual age when the I-130 prioirity date is current - the I-130 pending days
The I-130 pending days = The I-130 approval date - the I-130 filing date (find these two dates from the I-130 Approval Notice).
可以加的话会不会影响我嫂嫂的排期？
-No.
我哥和我侄子的排期是从现在开始还是10年前开始？
-Same as your sister in law.
另外帮亲属移民是不是收入越高越容易？
-It is helpful.
谢谢！
