Wow really? Lol I understood the whole message he or she is saying that they went to the AOS (ADJUSTMENT OF STATUS) Interview for green card but when they went to go check in and the clerk told him/her that name wasn't in the system because there's a DELAY at NBC (National Benefit Center) and that they haven't sent over paper work to a immigration interview officer because there's a delay at NBC (National Benefit Center) so basically they told to go home and that they will reschedule interview and notify threw mail when next interview is. This person is asking what can they do? I told him/her can't do anything but wait for the next interview appointment letter to come in the mail or she can call customer service or go to a INFOPASS and ask whats going on.
