immediate relative

Under U.S. immigration rubric, an immediate relative is the spouse of a U.S. citizen, an unmarried child under 21 years of age of a U.S. citizen, an orphan adopted abroad by a U.S. citizen, an orphan to be adopted in the U.S. by a U.S. citizen, or the parent of a U.S. citizen who is at least 21 years old.

Immediate relatives have special immigration priority and do not have to wait in line for a visa number to become available for them to immigrate because there are an unlimited number of visas for their particular categories.
