The correct answer to this open question is the following.
Make a list of various reasons why people have wanted to migrate from Mexico to the United States and why they have sometimes wanted to leave.
Well, Mexican immigrants to the United States have considerably diminished in the last 20 years. Today, a large number of immigrants come from Central American countries such as Guatemala, Honduras, Nicaragua, and El Salvador.
The reasons these people want to immigrate to the United States are first of all because they want to find a better job and make a decent living for themselves and their families. Another reason is that they are running from political persecution. Others are running from religious persecution. Some others want to enter the United States to go to college and make a career in a good school. But the majority of immigrants are looking for a better life trying to get a decent job in agriculture or the industries.
