I agree with that. Send them home first. Then we can sort it out with green cards or something like the Bracero program.
No green cards. Get the names, fingerprints and photos of each single illegal, send them back over the border. Then if they try to come back in and are caught, either instant jail or air drop them over a desert. They're all felons, not citizens, and are essentially invading. They don't deserve any rights here.
