回複：回複：Go infopass. COuld you tell me more specifically how

http://www.infopass.uscis.gov/

However so many people use this infopass for NC recently. Most likely the officer won't give you such info.

Here is my experience,

The lady checked her computer for 3-4 min and told me since my I-485 case is
pending she can't tell me my NC was clear or not.

I asked her again" Does this mean my NC is still pending and not clear yet?"
She told me again that she can't tell me if my NC was clear or not.

I'm sure she got something from the computer. She just doesn't want to tell me.
