A nonresident alien (NRA) is an individual who is not a U.S. citizen or Lawful Permanent Resident (aka Green Card Holder), or who does not satisfy the Substantial Presence Test. In general: • F and J student visa holders are considered non-residents during their first five full or partial calendar years in the U.S. • J professors and researchers are considered non-residents during their first two full or partial calendar years in the U.S. • H-1, TN and O-1 visa holders are considered non-residents until they meet the substantial presence test
