Illegal immigrants cross the border without papers by sneaking in most of the time. Sometimes illegal immigrants cross the border safely to meet other family members who live in the U.S. or to find jobs. Not all illegal immigrants cross the border between the U.S. and Mexico. Some cross through the U.S.-Canada border. Others come to the U.S. by boat. It is not easy to come to the U.S. illegally. A lot of time illegal immigrants that cross the border pay coyotes, or people who sneak immigrants in, an average of five thousand dollars to get to were they have to go. Even though all these things happen, sometimes things do not work out and illegal immigrants can die from all the traveling.
