How about we make a deal with Mexico about these immigrant families?

Set up safe zones for housing immigration candidates. Pay them for shovel-ready jobs with contractors building infrastructure in the border zone while letting them and their families live in US secured safe zones along the border regions. A family fleeing violence or poverty in this way can wait in a nice safe border village with plenty of food while waiting for their immigration claims to process.

A win for capitalism, national sovereignty, and humanitarian ethics all in one.
