The word "alien" is a technical, legal term for a person who is not a U.S. citizen. Common immigration terms are listed at the end of this section. Medicaid eligibility for aliens is based on whether the alien is a qualified or nonqualified alien. The previous category of lawful permanent resident becomes a subcategory of the new term qualified alien. The category known as permanently residing in the United States under color of law (PRUCOL) no longer applies and is no longer an eligibility classification. Individuals who were formerly PRUCOL are now considered nonqualified aliens.
