What food/lodging/such?
You find an illegal immigrant?
You immediately put them on the first, commercial flight, back to where they came from.
Whatever the cost?
I guarantee you it would pale in comparison to the tax dollars that go to support, illegal immigrants remaining in America.

Even if you flew 4 million, illegal immigrants from - say - Dallas to Bogota, Columbia (for example) by passenger airliner?

At roughly $400 per person.
That is $1,600 million per year for FOUR MILLION people flown home.
Still, far less than the government spends JUST in medical benefits for illegal immigrants...alone.
It would save taxpayers, HUGE amounts of money to ship all illegal immigrants, back home.
