Central Americans without documents now face increased security within Mexico, including checks on the train for stowaways. . . .
Isaac Castillo, owner of the Hotel La Posada in Arriaga, argues that Central American immigrants often end up working in Mexico, where wages can be double the few dollars a day they might earn at home.
"The problem isn't just in the U.S., but in Mexico, because a lot of Central Americans want to stay here and compete with Mexicans for jobs," he said.
