The growing globalization of the world economy and world's labor markets are facts. This is true for employers and workers in most globally competitive, high value-added, high skill, and high tech industries. Considering immigration globally, it is important to remember that the United States is not only a destination country, but also a source country for temporary and immigrant workers.
As an United States employer shall plan immigration and visa compliance well in advance of any temporary or permanent hiring of a new international worker for a United States payroll, likewise, any non-U.S. employer (or foreign branch or subsidiary of a U.S.-branch company) is well advised to plan for immigration and work permit compliance in other countries before putting United States or third country nationals on a non-U.S. payroll.
