He also wants to shut down Western Union:

Ending Illegal Immigration

We must stop the abuse of public education, welfare systems and our national integrity by securing our borders. Amnesty has not worked. We must stop the wholesale shipment of illegal immigrants’ earnings out of the country by Western Union et al and enforce existing laws that will remove the incentive to come illegally. At the same time, we must far more efficiently screen, qualify, and welcome those who prize liberty, learn and support our Constitutional values, want to work and contribute, learn English and apply legally. Qualified patriotic groups might help as sponsors.

Or does he mean that illegal aliens have to spend all their earnings here? He doesn’t flesh out his ideas very well.
