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):
