8老师好。前后咨询过您多次，非常感谢！
我给父母申请绿卡。我爸的绿卡刚刚拿到。可我妈的申请已经转到我家附近的移民局，好像是需要面试。我一直不太知道为什么两位老人一起申请，一个批了，一个需要面试。但因为我妈的指纹很模糊，打了两次，我猜可能是由于指纹不过需要面试。
刚才看了您给下面这位网友的回复，忽然想起一个问题，想向您请教。我父母的结婚证早就丢了。这次为了申请绿卡，特地回老家补办了一份。虽然上面标明是补办，但办证日期是去年，照片也是两位老人现照的。看了您给下面网友的回复，忽然想起，是不是我妈的绿卡申请是based on marriage。所以移民局只批了我爸的申请，而对我妈提供的结婚公证有疑问，需要面试
-Your mother green card application is not based on marriage either, but it is under your sponsor. Marriage based green card means the hu*****and sponsors the wife's green card or vice versa. Actually your mother does not need her marriage certificate, but your father need it only to prove you were born after your father married your mother.
