回复：help my RFE in NSC

Thank you so much for your reply.

Actually, I also asked my lawyear send it out by express mail, and from the tracking information it shows that the USCIS had already received the mail. But I never received any email notice saying that they already got it and there is no LUD since then. I am really worry about whether they place it in wrong place and my lawyear did something wrong. Thank you for your help.
