Multiply that by at least 10 years and that makes for about 2000 Chechens in the country.
But I was referring to Muslims. There are now *millions* in the U.S.
In fact while at war in Muslims countries, under Bush, the U.S. Government imported more Muslims into the U.S. than the previous two decades.
