Foreigners who’ve never been caught in the US can enter legally. Foreigners who are on the criminal alien lists, should never be allowed entry.
This way, Criminaliens here now are highly encouraged to self-deport. It’s their only chance they have to re-enter.
You are correct. Being in the US illegally should be an “A” felony with 20+ years in jail and deportation and a permanent ban on re-entry. A second conviction for illegal entry should be a capital crime with execution the next day after conviction.
Presently, we should give them 180 days to get their affairs in order and get out of the country. We should repeal the immigration act of 1965 and prohibit new immigrants until we can properly assimilate the ones we have here already.
