"We have consistently supported a legalization program which is both generous to the alien and fair to the countless thousands of people throughout the world who seek legally to come to America. The legalization provisions in this act will go far to improve the lives of a class of individuals who now must hide in the shadows, without access to many of the benefits of a free and open society. Very soon many of these men and women will be able to step into the sunlight and, ultimately, if they choose, they may become Americans."
