He was never given any information about where to call to attend in court and he got his license in 2015. When he leaves to Juarez for his interview will they dig this up and deny his petition? He has no other arrest than a dui in 2009. He completed work release and court probation.
He should show his paperwork to an experienced immigration attorney before going to Ciudad Juarez.
much more info needed.
however, if he did not do anything that was ordered then there would be an outstanding BENCH WARRANT for his arrest......and that will come up.
I am not an immigration lawyer and you need to consult with one.
