Under the system, the UNHCR considers those seeking to come to America before turning that list over to the United States to consider.

“Out of the four million-plus registered Syrian refugees in the region, UNHCR has so far submitted 22,427 cases to the United States for resettlement consideration. Of those, about 2,000 were accepted last year. The United States is welcoming Syrian refugees only from the 22,427 who made it through UNHCR referrals,” said the report from senior analyst Nayla Rush.

The report raised two huge issues. First, it found that the U.N. system is simply overloaded. Just consider this: Since there are over 4 million refugees and and 2,038 UNHCR staffers, each interviewer is responsible for vetting 2,100-2,800 refugees each.

And insiders have fretted about various types of fraud, where people can lie or pay their way through the U.N. system.
