The novel coronavirus delayed the arrival of seasonal immigrants who normally help harvest U.S. wheat,typically counts on migrants for about 30% of those kind of workers. The most common visa for migrant agriculture workers is the H-2A, which allows workers to stay in the United States for months at a time to work on farms. The number of H-2A visas granted for agriculture equipment operators rose to 10,798 from October through March, the typical hiring period for harvesters looking for a labor force that starts cutting wheat in May. Farmers and harvesting companies are having a hard time finding and keeping workers. Doug Zink said,"We had a lot of trouble getting our foreign workers over here," he said,they could not get flights.” The United States is the world's No. 3 exporter of wheat, a crop in high demand during the pandemic. A sustained labor shortage could impact the soy and corn harvests that start in September. source
