No, they did not provide us with exact details. I had to struggles 1 year to find out why exactly they denied with the waiver option only. Even then this does not makes sense.
No official notice, I reached out to senator office and have them email behalf of me to find out the actual reason. I believe that was not the main reason. I am not originally from Pakistan, I am a U.S. Citizen and my parents are from Bangladesh.
That was the official letter of denial notice. Nothing beyond that
