The best immigration reform policy would be to close the damn border and let them come in legally like it was always done before Biden.
Even when the border was closed except at check points, illegals would swim the Rio Grande. Why? Because they were criminals and no way they could make it through a check point. Anyone seeking a better life in the USA can get in legally if they have no record and they can provide legal ID. To get in quickly, one must have a legitimate destination such as a job and employer.
Only CRIMINALS enter illegally. End of story! If you commit a crime in the USA and are a citizen, you wouldn't flee to Mexico thru a checkpoint, but would cross illegally and hope the Mexican police didn't find you. They deal with "illegals" very harshly including torture in filthy prisons.
Illegals have no rights under the USA Constitution. They have no right to a day in court. Immediate deportation is totally constitutional and in the best interest of the country. What other country has open borders and rewards illegal crossers with more gifts than its tax paying citizens? Try crossing into Canada and not stopping when a guard yells halt. That ain't no toy gun they are pointing at you and they will pull the trigger for a clean kill shot.
Hundreds cross the border every day legally to work in the USA and then they return home, some daily, others weekly or monthly. Some get Visas for seasonal work which usually is a six month stay. Nothing novel about it.
I have one neighbor that does this and has for years. His kids were born here, so when school age, they stayed with other legal relatives when he and the wife returned to Mexico. Before school age, they went to Mexico with them. His wife died and he became a citizen. This was several years ago. He still goes to Mexico to his place every late fall and winter. Now, when here, he stays with his, now grown, kids that bought the place here from the relatives.
