No one should be allowed to enter the United States without a 100% comprehensive background check.
In the spring of 2011, it was reported that two Iraqi terrorists Waad Ramadan Alwan and Mohanad Shareef Hammadi were granted refugee status and brought to the United States and subsequently awarded U.S. citizenship.
This was allowed to occur despite the fact that the United States government officials had already caught them years earlier while they were still in Iraq and after they had admitted during interrogation that they were involved in terrorist attacks against Americans on behalf of Al-Qaeda. Alwan and Hammadi were not only let go, the United States government brought them into the United States as “refugees” who requested and successfully obtained asylum in America.
