Answer:
I don't know if this is just a personal answer thing, but for me, the US should of course allow legal immigrants to enter the US, but should have a different process for Illegal Imagrants.
Step-by-step explanation:
Without a border (with Mexico and America), drugs, gangs, and human trafficking occur. Of course, this could also block good people from coming in trying to have a better life. There is no perfect answer for this, but again, personally, I think that there should be a different system for these Mexican Immigrants.
