Mr. President I introduce. for appropriate reference. a bill to extend Public Law 78 for 2 additional years and to amend it to provide certain safeguards for the protection of domestic agricultural workers. The migrant farm workers constitute one of the most impoverished and neglected groups in our society. They have not generally shared in the rise of standard of living throughout the Nation and their social and economic problems continue to be most serious. The improvement of their opportunity for a better life is a matter of basic social justice. The bill which I am introducing today deals with only one phase of the whole migrant labor problem. that of the regulation of the conditions under which it shall be lawful to bring into this country Mexican nationals for agricultural labor. This is. however. a matter for which the Congress has special responsibility. since this program was established by the Congress in 1951 with the passage of Public Law 78. Although it was envisioned as a temporary measure. it has been extended on three occasions.
