For all the Bangladeshi, and Special registration group 4 in Chicago. I went to register while my I-130 was in process. Obviously I was quite concerned. I learnt at the registration that my case was approved, and I had an A#. As a result it went smooth. I walked in waited for three hours for my turn. I answered to the cross-verification question of the form designed for the registration. I was ready to go in about 15 min. I thought this experience might help other prospective registrer. Thank you.
