According to Michelangelo Landgrave of policymic, although, the immigration reform is dead, there is still a solution to the problem of legalizing the undocumented. The solution includes the expansion of North American Trade Agreement to include the labor market. If this system is implemented, citizens of any nation involved in the trade agreement would get to travel freely, work and live in the US.
Under the NAFTA provisions, individuals who are registered workers can also become naturalized US citizens. This way immigrants a fiscal cost to the US welfare system would also not arise. Such individuals would also need to pay their own private health insurance. It would also prevent mass immigration to the US.
Immigrants in the US are mostly from Latin American countries including Mexico. Since, these individuals would retain their home citizenship the pathway to citizenship for the 11 million undocumented would not arise. Seasonal farm workers would be able to travel easily back to their home country after the season ends. This way the agricultural labor shortage too would be addressed. Similar would be the case for other workers. Employers too would have access to more labor.
There are similar agreements elsewhere in the world such as the Schengen Area covering Europe, the common travel area in the UK and Ireland and many Central American countries. There would be major adjustments needed in this plan; however, such examples prove this can work if implemented well.
