There is an annual average domestic migratory work force of 427.0001958available in the United States to perform agricultural labor. Substantial segments of this force are used in every State of the Union at various times of the year. To replace the 437.600 Mexican nationals with the 427.000 domestic migrant workers would use up all of the available supply and leave a serious labor shortage in the remaining areas that have depended upon our domestic migratory labor. The northwestern area of the United States employs very few Mexican nationals. the great majority of our migrant agricultural labor coming from Texas and other southwestern States. The reason we do not use the nationals is quite simplethe nationals are recruited for a 6week period. and with our area located a great distance from Mexico. much of this 6 weeks time would be lost in traveling to and from the border. Not only would this time be lost. but the transportation costs would be excessive to our farmers.
