This is good -
1. secure the border
2. illegal aliens not allowed to work
3. current laws prohibiting employers from hiring illegals strictly enforced.
4. no welfare benefits
5. children born to illegals here are not US citizens.
6. hospital expenses incurred in US to be payable by Mexican government (or other county) - go through international court if US courts balk.
7. If a migrant agriculture labor program is renewed, illegal aliens not eligible - recruit from home country only (not US), with portion of wages earned payable upon their return.
The result of these measures will be massive self deportation.
One exception: "go through international court if US courts balk"
That could be a dangerous and slippery slope which could set presidence for the opposition (liberals) to use for their own agendas on strict gun laws, the death penalty...etc.
