回复：回复：回复：急急急，485被RFE 。我难道out of status过？

我还想问一下，F2签证的D/S 和这有关吗？

-Yes. D/S means your I-94 expires when your status expires (e.g. I-20 expires for F1/F2 students).

另外，能不能讲一下，245（k)在回复RFE的时候，具体怎么操作？

-You may not need to say anything about 245(k) at this time because USCIS should know this rule and they will not deny your I-485 just based on your unlawful presence <180 days. if they deny your I-485, you can file Motion to Reopen/Reconsideration using 245(k) rule. So, nothing worried.

Here is the link about 245(k):
