By definition, an undocumented student is a foreign national who:
- entered the United States without inspection or with fraudulent documents; or
- entered legally as a nonimmigrant but then violated the terms of his or her status and remained in the United States without authorization (as defined by the National Immigration Law Center).
In contrasts, a Lawful Permanent Resident (LPR) is defined as a person who was granted the right to live permanently in the United States. An LPR is a “green card” holder that is allowed to legally work and live in the United States.
