Sanga and Alan, thanks for your reply
Sanga, I will take your advice and skip going to Newark again.
Alan, i went on Feb 26, though we were called on Feb 25... We went on Feb 25, but INS was closed early due to power failure.
I spoke to the BCIS officer and asked about the second notice. She was not helpful, only that if the notice says disregard notice ,if you have done fingerprinting within 90 days, you have the option to disregard.
