Why is illegal immigration across the Mexican border so common?

The reason there are so much illegal immigration at Mexico borders is because many Mexicans want to live in the neighboring states like United States without passing the right way. Many of them seek to find a place with many opportunities so that their dreams can can be actualized. This problem of illegal immigration is being made complicated by the activities of human smugglers.

This set of people help anyone willing to cross the border illegally. Mexican immigrants in United States are about 12 million and they dominate a large percentage of immigrants in US, out of which 45 percent came through illegal means. Though effort is being made by Donald Trump led government to reduce the activities of illegal immigrants in the United States, this includes an increase in the number of law enforcement agencies at the southern border of the country so that the activities of human smugglers would be reduced. Also, Mexico's borders are too porous.
