请教8老师：我去年5月给我妈申请绿卡，去年11月份补了我的tax return的材料。今年7月I-130 批了，今天给移民局打电话，没问到情况，却收到了要interview的通知。Interview一般都会问什么问题？我们应该准备些什么？谢谢！
-Nothing special. Just review the information your mother provided in the I-485 and her answers should be consistent with the information in the I-485. Also, she prossibly will be asked whether she joined the Communist Party, etc.
