For immigrants travelling from Central America to the United States through Mexico, they are faced with some tough battles, forced to battle the Mexican drug cartels, corrupt police officers, and human traffickers, all this before they even come close to the US border.
But we assume that most immigrants trying to cross the US/Mexico border are all Mexican. The reality is that a large percentage of them come from Central America, and their journey north is grueling. For those hoping to get across the US border, they first have to pass through Mexico, an ordeal that often ends up being even more difficult than getting into the United States.
Most migrants cross into Mexico on rafts, via the Suchiate River. After that, they need to protect themselves from corrupt Mexican police, drug cartels like the infamous Los Zetas, and even fellow migrants. They often travel by foot and by pubic transit, but many of them ride on top of “the Beast,” the freight train that travel from the south to the north of Mexico.
