Lawful permanent residents satisfy the 40 qualifying quarters rule by accumulating ten years’ worth of Social Security work credits, either through their own covered earnings in the United States or by adding credits earned by a spouse during the marriage or by a parent before the immigrant turned 18. Reaching that number does two concrete things: it ends the financial sponsor’s obligation under the Affidavit of Support, and it lifts the bar on federal means-tested benefits like Medicaid and SNAP that otherwise restrict newer green card holders.1U.S. Department of Health and Human Services (ASPE). Overview of Immigrants Eligibility for SNAP, TANF, Medicaid, and CHIP
How a Quarter Gets Earned
The Social Security Administration doesn’t tie credits to the calendar. It counts them by annual earnings. In 2026, every $1,890 of covered wages or self-employment income earns one credit, capped at four credits per year no matter how much more you make. So $7,560 in covered earnings during 2026 maxes out the year, even if all of it came in one month. The threshold adjusts upward each year with the national average wage index.2Social Security Administration. Quarter of Coverage
For employees, FICA withholding does the work automatically as long as the employer reports the wages under the right Social Security number. Off-the-books pay produces no credits. That’s why checking your earnings record matters, and it’s the single most common way immigrants find themselves short of the count they expected.
Self-employed workers get credits too, reported through Schedule SE with the annual tax return. You need at least $400 in net self-employment earnings for the income to count, and the same $1,890-per-credit rule then applies.3Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)4Social Security Administration. How You Earn Credits The IRS also allows optional calculation methods that let self-employed workers pick up credits in low-profit or loss years by paying a bit more self-employment tax. The nonfarm optional method is capped at five lifetime uses, so it pays to plan when to use it.
Using a Spouse’s or Parent’s Credits
You don’t have to earn all 40 yourself. Federal law lets you combine your own credits with certain family members’ credits to reach the threshold.5Office of the Law Revision Counsel. 8 USC 1645 – Qualifying Quarters
- Quarters your spouse earned during your marriage, if you remain married to that spouse or the spouse has died.
- Quarters a parent earned while you were under age 18.
The spousal rule has a hard edge. Divorce ends the credit-sharing, no matter how long the marriage lasted. The statute is explicit: the immigrant must remain married to the spouse or the spouse must be deceased.5Office of the Law Revision Counsel. 8 USC 1645 – Qualifying Quarters This is not the same as the Social Security retirement rule that lets a divorced spouse claim off a former partner’s record after a ten-year marriage. For the immigration count, divorce cuts the tie.
Quarters That Don’t Count
A quarter earned after December 31, 1996, doesn’t count toward the 40 if the person who earned it received a federal means-tested public benefit during that same period. That applies to your own quarters and to any credited from a spouse or parent.5Office of the Law Revision Counsel. 8 USC 1645 – Qualifying Quarters6Office of the Law Revision Counsel. 8 USC 1183a – Requirements for Sponsors Affidavit of Support The disqualifying programs include Medicaid, TANF, and SNAP.
The result is a hard tradeoff. The same benefits a family may need while building toward 40 quarters can erase the quarters they’re earning during the same window. Before accepting one of these benefits, it’s worth thinking about whether it will push the 40-quarter date further out.
What 40 Quarters Unlocks
The 1996 welfare reform generally bars most immigrants who arrived after that date from federal means-tested benefits during their first five years as permanent residents. Reaching 40 qualifying quarters is one way past that restriction. Lawful permanent residents credited with 40 quarters are required to be covered by states for programs like Medicaid and SNAP on the same terms as citizens.1U.S. Department of Health and Human Services (ASPE). Overview of Immigrants Eligibility for SNAP, TANF, Medicaid, and CHIP
Refugees, asylees, and certain veterans are exempt from the five-year wait on other grounds. For a typical family-sponsored green card holder, though, the 40-quarter count is the primary path back into safety-net eligibility, and falling short can mean continued exclusion even after a decade of residency.
What 40 Quarters Ends for the Sponsor
A sponsor who signs Form I-864 commits to keeping the immigrant’s income at no less than 125% of the federal poverty guidelines. That commitment is legally enforceable: the government can seek reimbursement for certain benefits used, and the immigrant can sue the sponsor for failing to provide support.6Office of the Law Revision Counsel. 8 USC 1183a – Requirements for Sponsors Affidavit of Support
The obligation ends on a short list of events:
- The immigrant naturalizes.
- The immigrant is credited with 40 qualifying quarters, none of the post-1996 quarters tainted by means-tested benefits.
- The immigrant dies.6Office of the Law Revision Counsel. 8 USC 1183a – Requirements for Sponsors Affidavit of Support
Divorce is not on that list. A sponsor who divorces the immigrant they sponsored remains financially responsible until one of the statutory events occurs. Courts have consistently enforced the obligation against ex-spouses who assumed the divorce ended it.
Foreign Work Credits Are a Separate Track
The United States has Social Security totalization agreements with roughly 30 countries, including Canada, the United Kingdom, Germany, Japan, South Korea, and most of Western Europe.7Social Security Administration. Status of Totalization Agreements Those agreements let workers combine credits from both systems to qualify for Social Security retirement or disability benefits.
They don’t help with the 40-quarter immigration count. USCIS guidance defines qualifying quarters by reference to work performed in the United States with earnings meeting the SSA threshold.8USCIS. Affidavit of Support Under Section 213A of the INA Years worked abroad before immigrating may support a future retirement check, but they generally will not count toward ending the Affidavit of Support or unlocking federal benefits.
Checking Your Credits and Fixing Errors
The fastest way to see your total is a free “my Social Security” account online. It shows credits earned and yearly earnings history. For an immigration matter that needs official proof, you can request a formal record with Form SSA-7050-F4; a certified itemized statement, which lists years and employer names, runs $96 and is what attorneys typically ask for.9Social Security Administration. Form SSA-7050 – Request for Social Security Earnings Information
If credits are missing, gather what you can: W-2s, tax returns, pay stubs, or any record of the work and wages. Contact the SSA with the documentation and it will work with you and former employers to correct the record.10Social Security Administration. How to Correct Your Social Security Earnings Record If you can’t find paperwork, write down employer names, locations, dates, and approximate earnings from memory. Corrections take time, so start well before any filing deadline. Earnings from the current year or the one just ended may not have posted yet; check again after August of the following year before assuming there’s an error.
