Much immigration practice is centered on only a handful of the nonimmigrant visa categories in the Immigration and Nationality Act (INA). Every day we encounter those familiar letters—H (for the H-1B professional visa type), L (for intracompany transferees), O (for O-1 artists and their O-2 essential support personnel), not to mention B (the ubiquitous B-1/B-2 for tourists and temporary business visitors). But the same section 101(a)(15) of the INA offers a true alphabet soup, and I decided to take a gander at some of the lesser-known visa types.
