I didn't mean to be mean-spirited - that's honestly how I read your post - I will concede I seem to be in full-defense mode on this thread, so I could have just given you a knee-jerk reaction. I'm glad you don't think that.
Now, please read this section from HR 4437:
". . . assists, encourages, directs, or induces a person to reside in or remain in the United States, or to attempt to reside in or remain in the United States, knowing or in reckless disregard of the fact that such person is an alien who lacks lawful authority to reside in or remain in the United States;"
How can you guarantee that section of the law will NOT be used against private charities?
"How can you guarantee that section of the law will NOT be used against private charities?" VERY SIMPLE: IT'S ALL ABOUT NUMBERS. By the way if a "hot meal" was illegel I'm sure a sandwich would suffice. We are to live peaceable with all men afterall. You could GO INTO the world and feed them their hot meal in their legal home.
