Mexican migrants were used to be very important element of the US agriculture system back in the years. They were doing low-skilled farm works, many Americans do not want to do.

Mexican economy has also grew successfully, and many people there just don't want to work in the US anymore.

Now, the farmers are blaming a shortage of immigrant labour in the country.
