SPLC researchers interviewed approximately 150 women who are either currently undocumented or have spent time in the U.S. as undocumented immigrants. The women all have worked in the U.S. food industry in Arkansas, California, Florida, Iowa, New York or North Carolina. A few have now obtained legal status. The interviews took place from January through March of 2010. Researchers also interviewed a number of advocates who work with immigrant women and farmworkers.
