In at least 150 words, compare and contrast the experiences of Midwestern migrant farmers with those of Mexican migrant farmers.

The supply of farm labor has become one of the most significant issues in U.S. immigration policy. During the early twenty-first century, the U.S. Department of Labor’s National Agricultural Worker Survey reported that 77 percent of all workers on American crop farms had been born abroad, that almost half the foreign-born workers had been in the United States for fewer than five years, and that more than half were not legally authorized to work in the United States.
Commercial farms in the western United States have long depended on workers from other countries. Most foreign farmworkers stay only long enough to earn target amounts of money and then return to their home countries. Some do remain in the United States, but their American-educated children rarely follow their parents into the fields. Consequently, much of the American agricultural industry has remained on a immigration treadmill, needing constantly to recruit new foreign workers willing to accept seasonal jobs.
