What is the difference between a “non-immigrant visa” and an “immigrant visa”?
Those who are traveling to the U. S. for a temporary purpose are categorized under United States law as non-immigrants as they do not intend to remain indefinitely. These individuals are required to obtain a “non-immigrant visa” (NIV). Individuals traveling to the U.S. to live and work on a permanent basis are classified as immigrants and therefore must obtain an “immigrant visa” (IV) which permits them to stay indefinitely.
