I don't think it applies to folks on H or L visas. Wording from the site:
"Nonimmigrants, like students, temporary workers, or people on tourist visas, come to the U.S. for a short time and for a specific purpose. Our system is designed for them to leave when their visit is over. Their visit should not function as the first step in the Green Card process. "
