The US house of representatives has recently passed a bill to slow down the flow of refugees in country. They have suspended the admission of Syrians and intensify the screening of the refugees.
The main concern of the FBI is that no Syrian should poses any risk of the security as they can’t keep US’s security at risk.
Some Republicans have said that some refugees can be militants and it is important to screen refugees properly. This would be the strictest screening ever from a war – torn nation.
