This document is a transcript of a hearing on provisions of the Immigration and Nationality Act that govern the entry and the stay of certain classes of nonimmigrants, including temporary or H-2 workers and foreign students. The hearing also reviewed the proposal to amend the Immigration and Nationality Act so that visas could be waived for nationals of certain countries that have a reciprocal provision for visa waiver for citizens of the United States entering their countries. Finally, the hearing examined the most recent efforts of the Immigration and Naturalization Service in maintaining an adequate system for immigrant document control. Testimony and prepared statements were given by officials of the United States Department of Labor, Department of Agriculture, and the Immigration and Naturalization Service; by officials of various trade associations (such as the Florida Fruit and Vegetable Association and the American Pulpwood Association); and by migrant rights organizations. Those testifying assessed the provisions of the H-2 program on their groups' interests and offered some alternative amendments to the Act. (KC)
