请问8老师, 我帮助妹妹， 妹夫 和他们的 女儿移民来美。 刚收到移民局的郵件。
-What kind of 郵件? If it is NVC 郵件 for the immigrant visa application, your sister and her family member have to submit the application within one year from the date NVC informed you. Otherwise, the entire case will be cancelled.
Yes, the mail was from NVC. Thanks for your explanation for first part.
目前我妹妹女儿19 岁， 大学二年级，想来美读硕士。我妹一家还没有准备好移民来美。
