03/22/2018 Interview. Letter
04/22 interview
I had an early appointment and was there 1 hour before.
I went with my lawyer and I brought all the necessary items requested neatly in a folder. Got called about 15 min after my appointment. I got approved for my i-130 and i-485 is pending due to a system failure with my fingerprints.He said not to worry as soon as that is settled he will approve the case.
 
Didn’t ask that many questions just how my wife and I met? Where did we get married? Where I proposed? When we started dating?
The IO was very nice and I felt comfortable . He went through all the questions on I-485 and then he said we are moving forward with the case. That’s when he said he had an error transferring finger prints. My lawyer asked if there was anything wrong and he mentioned is his system and within 3 days he should have it approved. I won’t be an ease until case status changes, receive letter of approval or card in hand.

Now he gave me the infamous white paper to wait 120 days. My case status still is at interview scheduled and I-130 is still in received On the app and online.

Anyone had this issue before I have no bad record but not sure if something popped out and he but it on hold. My understanding they did this before interviewing me. Any how hope everything goes well and wanted to share my experience. I will keep an update
