In the section III of Chertoff's testimony,
In addition to these proposed modifications to the H-2A program, we continue to work with federal partners on a number of other reforms announced last August to improve our temporary worker programs. These include reforms of the H-2B program for temporary or seasonal non-agricultural workers; an extension from 1 year to 3 years of the period that professional workers from Canada and Mexico may stay in the U.S. under the TN visa program; and potential improvements to visa programs for high-skilled workers. We will continue to keep the Committee apprised as these efforts proceed
