When the US closed its border after the Immigration Restriction Act of 1921. Before that, many people from Mexico used to work in the United States and returned back to their homes in Mexico. This Act effectively started the illegal immigration problem, as many people had to furtively look for jobs at the risk of being deported back to Mexico.
