We could build internment "asylum" centers all along the southern border. These could be pre built and have sanitary facilities and tents. Some could have FEMA trailers. As soon as the aliens cross we apprehend them and put them in the camps. They are processed and KEPT there until they are deported. That is a workable and simple solution. Handle this like a natural disaster. Also, as soon as we started doing this the word would get out and the horde would stop coming.

How many law enforcement will it take to stop hundreds crashing the border at once with thousands immediately behind them following them in forcefully?
