My main concern is how do they verify if someone from Iran, Libya, Somalia, Sudan, Syria and Yemen has a “bona fide” relationship with a person or entity in the United States.  Also how long does it take?  Do they need to provide documents to prove their relationship?  And do they check to see if these documents are not fake?  Or do they just ask the person in the U.S. and a verbal answer is sufficient?  I wonder how someone would show that a person in the U.S. was their grandmother or grandfather and what documents they would need?  To me it's not that easy if they're going to do a good job in clearing someone for entry into the United States.
