The Great Depression destroyed most “aspects of American life, and immigration was no exception” (Daniels, 59). The Great Depression that occurred in 1929 was a worldwide despair. The changed conditions forced large numbers of people to leave, some using their own resources and others being assisted by the US government. During this time, he caused the American government to give each country a maximum number of people allowed to enter the country and did not bother Latin American or Canadian immigrants. Mexican immigrants working in the United States have become very important to the country's economy. Later, in the 1950s, approximately 200,000 Mexicans crossed the border without permission. They worked hard in unfavorable conditions and accepted lower wages than native workers. During the 1930s, the number of people leaving the United States had exceeded those arriving. As Americans faced difficult times due to the Great Depression, the “LPC Clause” was passed by President Hoover to prevent Mexicans from immigrating to the country. By 1848, the 80,000 Mexicans living on what was developed American soil could move to what remained of Mexico or continue to stay and automatically become citizens of the United States. The Great Depression caused Mexican workers to move from job to job and budget losses. Robert Divine, a historian, describes that when the immigrant replied “that he was waiting for work there; the anti-contractual labor clause could be used to deny entry permission.” This means that an official would ask an immigrant if he is looking for work in the United States and if the answer was yes he would be denied entry into the country.
