A lawful permanent resident who is not a U.S. citizen may become eligible for Medicare Part A at age 65 only if the person:

Why A is correct

Medicare eligibility for a lawful permanent resident who is not a citizen requires at least 5 years of continuous residence in the United States, in addition to meeting the insured-status (work credit) requirements or qualifying to buy into Part A. The 5-year residency rule is the statutory test the exam expects. A green card alone, sponsorship, or a brief tax-paying history does not satisfy the residency and insured-status requirements. The 5-year residency test is a distinct statutory requirement for non-citizens.

Why the other options are wrong

• B) A green card alone is not enough; the 5-year continuous residence requirement must also be met. Continuous residence in the U.S. for at least five years is the additional statutory condition for Part A.
• C) Sponsorship is an immigration-law concept and plays no role in the Medicare residency test. Sponsorship is an immigration-law concept with no role in Medicare's Part A eligibility rules whatsoever.
• D) A single year of tax payments is far short of the statutory standard; Part A turns on 5 years' residence plus credits or buy-in. The statutory standard is residence and credits, not taxes.

Memory hook

Five years on U.S. soil earns a lawful resident a Medicare welcome. Green card alone? Not yet.

Why A is correct

Medicare eligibility at age 65 extends to U.S. citizens and to lawful permanent residents who have lived continuously in the United States for at least five years. This five-year residency requirement is designed to ensure that newcomers have contributed to and been part of the Medicare system's beneficiary population before receiving benefits. A lawful permanent resident under age 65 or with less than five years of residency does not qualify under this rule.

Why the other options are wrong

• B) One year is far short of the five-year continuous residency requirement for legal residents.
• C) Medicare is a federal program; state residency is not the controlling requirement.
• D) A residency requirement does exist for lawful permanent residents: five continuous years in the United States.

Memory hook

65 plus citizen, or legal resident in the U.S. for 5 years, unlocks Medicare. Five years is the magic residency number.
