今年帮母亲办绿卡的时间线和问题

我今年6月底帮母亲交的绿卡申请，I-130和I-485 concurrent, 8月15号打指纹然后I-485更新为active review, estimated time 3 months。然后12月2号I-130更新为active review，但是estimated time变成12个月了，我给我妈买的2月底回国的机票，原本觉得6个月可以搞定了，哪知道要等那么久了。我是不是该改机票了还是再等等？

我觉得可以再等等，一般130 approve 后485很快

probably best to stay in the US until she gets greencard approved. it took us almost 18 months waiting, don't know why. I heard some other parents got greencard within 6 months. We filed I-130 and I-485 together, and by the time, my parents got greencard, I-130 was still pending. Good luck!

我们从active review 到approve 搞了10months，从交申请到拿到卡14months，就一个data point

我给我妈办的是130,485分开申请，之后又申请了返美证。申请受理后的一个月后通知打指纹， 4个半月的时候485批了，隔了几天130 也批了，两周后收到绿卡，再一周后收到社安卡。 只有返美证到现在都没下来。

我们可能是同一批递交的,到https://www.casestatusext.com/cases输入I-485 receipt#, 可以看到相近receipt#被批了几个了
