Every family-based green card needs a sponsor who signs Form I-864 and promises to support the immigrant financially. It is the step that quietly sinks a lot of otherwise straightforward cases — usually because the sponsor didn't realise how the maths works, or didn't realise what they were signing.
The basic rule
The sponsor must show income of at least 125% of the Federal Poverty Guidelines for their household size. (For a sponsor on active duty in the U.S. armed forces sponsoring a spouse or child, the threshold drops to 100%.)
The Guidelines are updated every year, and the exact dollar figures for 2026 are published on the USCIS I-864P page. Use that page — not a number you read in a forum, and not last year's chart. This is the one place where an out-of-date figure will get your case rejected.
Counting your household correctly
People underestimate this and come up short. Your household size includes:
- You, the sponsor
- Your spouse
- Your dependent children
- Anyone else you claim as a dependent on your taxes
- The immigrant you're sponsoring — and any dependants immigrating with them
- Anyone you've sponsored before on a previous I-864 whose obligation hasn't ended
Forgetting that last one catches out repeat sponsors surprisingly often.
What counts as income
USCIS looks primarily at the total income line on your most recent federal tax return. Not gross pay, not what you think you'll earn — the number you told the IRS.
If your current income is genuinely higher than last year's return (a new job, a raise), you can show that with recent pay stubs and an employer letter. But expect the tax return to be the anchor. If those two numbers tell different stories, be ready to explain why.
If you don't earn enough
Falling short is common and it is not the end. There are three routes:
1. Use assets
Assets can make up the gap — savings, property equity, investments. They're discounted: generally you need assets worth 5× the shortfall (or 3× when a U.S. citizen is sponsoring a spouse or child). Assets must be genuinely available — you'd have to be able to convert them to cash within about a year without hardship.
2. Add a household member's income (Form I-864A)
Someone living with you — often an adult child or a parent — can contribute their income if they sign an I-864A. They must actually live in your household.
3. Find a joint sponsor
A joint sponsor is a separate person who meets the requirement on their own. They must be a U.S. citizen or permanent resident, at least 18, living in the U.S., and they take on the full obligation independently. They do not need to be related to anyone.
What you are actually signing
The I-864 is a legally enforceable contract with the U.S. government — not a formality. If the immigrant receives certain means-tested public benefits, the agency can seek reimbursement from you. The immigrant themselves can sue you to enforce support. And here is the part that shocks people: divorce does not end the obligation.
The obligation ends only when one of these happens: the immigrant becomes a U.S. citizen; they earn 40 qualifying quarters of work (about ten years); they permanently leave the U.S.; they die; or the sponsor dies. Nothing else — not a break-up, not a change of heart.
This is not written to frighten you. It's written because a lot of people sign an I-864 as a favour to a friend or a new in-law, without ever being told it can follow them for a decade.
The documents you'll need
- Your most recent federal tax return (or an IRS tax transcript — usually cleaner and easier to obtain)
- W-2s and/or 1099s for that year
- Recent pay stubs, if current income differs from the return
- An employer letter confirming the job and salary, where helpful
- Proof of U.S. citizenship or permanent residence
- Evidence for any assets you're relying on

Can the immigrant's own income count?
Sometimes — if they're already lawfully working in the U.S. and their income will continue from the same source after they get the green card. It's a narrower path than people assume, so don't build the case on it without checking.
I haven't filed taxes for some years. What now?
If you were legally required to file and didn't, that's a problem to resolve before you sponsor anyone. Consular officers and USCIS both ask. Fix the filings first; it's slower, but it's the only way through.
Does a joint sponsor have to be family?
No. A friend, a colleague, anyone eligible can be a joint sponsor — provided they understand they're taking on a real, enforceable obligation.
