I was talking to the OP. He/she said "when I put a job opening out, a few applicants are foreign workers asking I take on their Visa costs, but there are dozens of better qualified U. S. Citizens applying for the same job".
All I was saying was hire the dozens of better qualified US citizens and make sure you can measure and prove the benefit to thhe business of your choice. You aren't a grinch at all unless you are in a position to hire staff, prefer off shore candidates, then moan about it.
