We issue green cards as a privilege for foreigners to enjoy our hospitality and opportunity. It's too bad they experienced a temporary inconvenience for the sake of our security. Those who complained or protested should be deported posthaste. I know it doesn't play well with the media but they have lost their iron grip and perhaps it is time to shape modern American culture.
I'm sure there are more than a few alien RATagandists that need to go bye-bye.
