Just an observation: Since we are no longer issuing visa's, it won't be long before ALL foreigners that are still here will be considered here illegally. Hence, law enforcement will have every right to pick them up, hold them and interrogate them.
However, deportation is not good enough for me. Anyone caught illegally in this country should be imprisoned for 5 years of hard labor. What kind of labor? Well, maybe the construction of a 3000+ mile border wall to our north and south would be a good start. What do you think? It sure beats just sending them back so they can return to Canada and just walk back into the US.
If the only punishment is deportation, thats like telling bank robbers that if you get caught, your only punishment is having to give the money back.....IMHO
