1. MYTH: The biggest influx of undocumented immigrants comes from people sneaking in through our uncontrolled border.
Though we often portray the border as an uncontrolled area, between 2014 and 2015, border agents have actually more than doubled, while illegal immigration has actually decreased. But even with the increase in security (or even if we built more walls), this may not necessarily affect illegal immigration. This is because most undocumented immigrants don’t enter illegally through the border, but instead simply overstay a tourist visa once they’re already here.
