No.
我妈妈要10月底来美国我才帮她申请,而且听你的意见要等3个月
我想在这个月给我姐姐递交材料,请问我提前交姐姐的材料会影响母亲吗?
-No.
我只给姐姐一个人移民,她有个女儿倒是可以现在一起申请,问题是那个时候她超过21岁,是不是没有必要我帮她女儿申请呢?
-You can only file one I-130 for your sister now. if her kid is not age-out when the priority date is current more than 10 years later, then the kid can apply for the immigrant visa/green card together with her mother.
还是等我姐姐再帮她女儿申请?
