My brother in law had confirmed seats and was going to be traveling to U.S (from Karachi Pakistan) with his parents to visit his sister (my wife). He got a call from Emirates 3 hours before the departure time telling him that they cannot let him board the flight, per the instructions from the local U.S embassy. Emirates told him to contact U.S embassy immediately. U.S embassy was obviously closed at that time. Emirates also canceled his flight later. He still has to figure out how he will get his refund back from the airline 9or the travel agent) but he is baffled at the sequence of events that have occured. He has a valid passport that doesn't expire for another 3 years. He has a 5-year multiple entry visit Visa to the U.S. He has travled here twice before. He is going to contact the U.S embassy on Monday first thing but this has upset his entire plans and left him frustrated to not be able accompany his parents. His parents boarded flight alone and they are on the plane as I am typing this.
I wanted to know if anyone has this ever happened before or even remotely heard about somthing similar or have insights, opinions or just thoughts and comments, I would REALLY like to know.
