Read above. You need to transfer your jobs to mexica. So mexicans will work at home.Well it's a multi-facitated problem, but parts to the solution include:
Stabilizing Mexico - most drugs come from or through Mexico.
Drug Legalization and reschedualing and treatment to starve cartels of finances.
Demanding fair, legitimate elections in Mexico to get control of the border.
Stronger border patrol presence, especially with drones.
Demand the Mexican Government allow us to pursue criminals into its territory - it is idiotic if a criminal crosses a river or an invisible line they can be nearly completely safe.
Greater pressure on job creators to hire documented americans
Much stronger penalties on those hiring illegal workers
An amnesty program designed to help integrate those people here, quickly and efficiently, including payment of back taxes, citizenship oaths and required learning of conversational English.
Developing programs to allow those who work here temporarily (farm workers, construction, landscaping, ect.) to return home legally and safely and quickly.
