According to the search results, the crops picked by migrant farmworkers in the United States vary depending on the region and the season. However, some of the most common crops picked by farmworkers include:

It is important to note that not all agricultural workers are migrant workers. In fact, around 85% of hired crop farmworkers are considered settled, meaning that they work at a single location within 75 miles of their home. However, according to the National Agricultural Workers Survey (NAWS), the majority (70%) of agricultural workers were foreign-born. Additionally, immigrants play a crucial role in the agriculture industry, with almost 57% of crop production workers being immigrants in 2019.
