Yes. Lawful permanent residents — green card holders — can collect Social Security benefits in the United States. Immigration status alone does not disqualify you. What matters is whether you've worked enough years in the U.S. and paid Social Security taxes during that time.

The Social Security Administration (SSA) does not distinguish between citizens and green card holders when it comes to retirement, disability, or survivor benefits. If you meet the work and age requirements, you qualify — period.

What about undocumented immigrants? Generally, no. The SSA requires lawful presence to collect benefits. Undocumented immigrants may pay Social Security taxes through their work, but they are not eligible to receive retirement or disability benefits based on those contributions.

Social Security eligibility is built around work credits. The SSA uses credits to measure how long you've paid into the system. In 2026, you earn one credit for every $1,810 in covered wages or self-employment income, up to a maximum of four credits per year.

To qualify for Social Security retirement benefits, you need 40 credits — the equivalent of 10 years of work. This is the same requirement for U.S. citizens and green card holders alike.

A few important rules for green card holders:

• Only work performed in the United States counts toward your 40-credit requirement under regular Social Security rules.
• Credits accumulate on your record and never expire. If you worked in the U.S. for several years, left, and came back, those earlier credits are still there.
• You can earn credits as a green card holder or on certain work visas before you got your green card. The requirement is simple: you must have been authorized to work and paid Social Security taxes at the time.

Disability benefits have a lower credit threshold depending on your age when the disability occurs. Survivor benefits for a spouse or children also have reduced credit requirements. The SSA's website provides the specific credit thresholds for these benefit types.

If you worked in another country before coming to the United States, those years may not be lost. The SSA has negotiated totalization agreements with more than 30 countries. These agreements allow workers to combine — or "totalize" — work credits earned in both countries to meet the eligibility threshold for benefits.

For example, say you worked eight years in the U.S. and six years in a country with a totalization agreement. You may be able to combine those credits to meet the 40-quarter requirement. Each country's agreement has its own rules, so the outcome depends on where you worked and for how long.

For a full list of countries with active totalization agreements and details on how each one works, visit the SSA's international programs page.

Qualifying for Social Security and getting the most out of it are two different things. The way SSA calculates your benefit can work differently for immigrants than for lifelong U.S. workers — and in some cases it actually works in your favor.

SSA calculates your retirement benefit using your average indexed monthly earnings across your 35 highest-earning years. Here's where it gets interesting for immigrants: years you spent outside the U.S. count as zero-income years in that average. If you only worked in the U.S. for 15 years, SSA averages your earnings over 35 years — meaning 20 of those years are treated as $0 income.

This lowers your average and therefore your monthly benefit amount. However, the SSA's formula is weighted to favor lower-wage workers. Because of this, immigrants with shorter U.S. work histories can sometimes receive a proportionally higher return on their contributions than long-term U.S. workers.

The practical takeaway: the more years you work in the U.S. and pay into Social Security, the higher your monthly benefit will be. Every additional year of U.S. work improves your calculation.

Many immigrants eventually retire to their home country or split time between the U.S. and abroad. Social Security does not stop at the U.S. border — but there are rules.

Generally, the SSA cannot pay retirement, survivor, or disability benefits to noncitizens who have been outside the United States for six or more consecutive months. Once you leave for that long, payments stop until you return to the U.S. for at least 30 consecutive days.

However, there are important exceptions:

• If your country has a totalization agreement with the United States, you can generally receive benefits abroad without interruption.
• Citizens of certain countries — including most of Western Europe, Canada, Japan, and others — can receive payments abroad indefinitely based on SSA country-specific rules.
• U.S. citizens face no restrictions on collecting Social Security abroad, which is another meaningful advantage of naturalization.

The SSA offers a Payments Abroad Screening Tool that lets you check whether your specific situation allows for continued payments outside the U.S.

Spending significant time outside the U.S. as a green card holder can affect more than just your benefits. See our guide on working abroad as a green card holder to understand how extended absences affect your immigration status.

Social Security retirement benefits and Supplemental Security Income — SSI — are two separate programs. It's easy to confuse them because both are administered by the SSA, but they work very differently for immigrants.

SSI is a needs-based program. It provides monthly cash payments to people who are 65 or older, blind, or disabled and who have limited income and resources. It is not based on work history.

For green card holders, SSI eligibility is more restricted than regular Social Security:

• You must have been a lawful permanent resident for at least 5 years before you can apply.
• You generally need 40 qualifying U.S. work quarters to be eligible — either your own or credits from a parent or spouse.
• Quarters in which you received means-tested public benefits do not count toward the 40-quarter total.

Some states offer their own supplemental programs for immigrants who don't qualify for federal SSI. California's Cash Assistance Program for Immigrants (CAPI) is one example. If you've been told you don't qualify for SSI, it's worth checking what your state offers.

Becoming a U.S. citizen doesn't change how much Social Security you've earned — your work record and benefit calculation stay the same. But naturalization removes several restrictions that apply to green card holders.

As a citizen, you can collect Social Security benefits anywhere in the world without interruption. You are no longer subject to the six-month abroad rule. You are not required to return to the U.S. to restart payments. And you face no immigration-status-related barriers to SSI eligibility after naturalization.

For immigrants who plan to retire abroad or want to move back to their home country someday, this is one of the most practical benefits of U.S. citizenship there is.

If you've been a green card holder for at least five years, you may already meet the basic citizenship requirements to apply. And if you're weighing the differences between staying a permanent resident and naturalizing, our guide on permanent residence vs citizenship lays out the full picture.
