What kind of hardships did Mexican immigrants face ONCE they arrived in the U. S.?

The Great Depression of the 1930s hit Mexican immigrants especially hard. Along with the job crisis and food shortages that affected all U.S. workers, Mexicans and Mexican Americans had to face an additional threat: deportation. As unemployment swept the U.S., hostility to immigrant workers grew, and the government began a program of repatriating immigrants to Mexico. Immigrants were offered free train rides to Mexico, and some went voluntarily, but many were either tricked or coerced into repatriation, and some U.S. citizens were deported simply on suspicion of being Mexican. All in all, hundreds of thousands of Mexican immigrants, especially farmworkers, were sent out of the country during the 1930s--many of them the same workers who had been eagerly recruited a decade before.
