去年就收到了移民局亲属移民的邮件通知：
NVC will work with the U.S. Embassy/Consulate General in GUANGZHOU, CHIN to schedule an interview appointment for you. Once we have confirmed an interview date, we will send a notice to you, your petitioner, and attorney (if applicable).
说所有材料都已经准备好了，他们会和广州大使馆定一个面试时间，但到现在还没有任何消息。请问一般情况下需要等多久？
-Case by case, hard to say exactly. If your priority date is current based on A Form, it should be soon (probably a few nonths to one year)
流程上是他们定个时间，然后我们按时去？
-Yes.
还是定一个时间范围，我们选时间？我在网上没有查到什么面试信息，大家有什么攻略链接吗？
