Refugees apply for status as "asylum seeker" in the USA.
There is sufficient data to show that only 15% to 30% of those making such claims are granted asylum seeker status. Anyone can walk in and say "I am fearful of the government in my countryv therefore I need asylum in your country". Can anyone prove if this is true or false? A UN study some time back also said the same thing -- about 15% are genuine.
The fact that able-bodied military age males predominate from the southern border (almost 65%) as established by the Heritage Foundation shows that they are not asylum seekers. The seekers would be coming with families, not trying to storm the border.
