SAMUEL P. HUNTINGTON, author of The Clash of Civilizations, calls migration “the central issue of our time.”7 He divides immigrants into the “converts” who come to assimilate to our way of life, and “sojourners,” who come to work a few years and return home. “New immigrants” from south of the border, he writes, “are neither converts nor sojourners. They go back and forth between California and Mexico, maintaining dual identities and encouraging family members to join them.”
