a) Border crossings
b) short visa overstays
c) Been in USA for 40 years, working and paying taxes
d) Legal green card holders
As it continues, I expect:
e) Raiding the IRS for locations of all tax-paying workers
f) More veterans and welfare program elimination
g) All public schools dismantled and elimination of vouchers
h) Further targeting of single mothers
i) City raids based on demographics for rounding up to go to private unaccountable prison facilities to profit from free labor force
j) Forbidding non-English speaking
k) Social network database for political opinions and removal of civil rights, possible imprisonment for more free labor.
and these will all fall in line with stuff the right has been complaining about for decades.
