TL;DR: A prenup does not block a marriage-based green card, and USCIS does not deny applications because a couple signed one. According to USCIS, a sponsor who signs Form I-864 agrees to support the immigrant at 125% of the Federal Poverty Guidelines, and divorce does not end that obligation. Most federal courts have held a prenup cannot waive it.
If you are sponsoring a partner for a green card, or being sponsored, the prenup question can feel loaded. A common worry runs like this: if we sign a prenup that limits financial support, will it look like the marriage isn't real, or will it sabotage the immigration case? The reassuring part comes first. A prenup does not block a marriage-based green card, and USCIS does not deny applications because a couple has one. What a prenup cannot do is erase a separate financial promise the sponsor makes to the U.S. government when they sign Form I-864.
If you are still deciding whether a prenup makes sense at all, our primer on what a prenup is and whether you need one is a good place to start. This post focuses on the narrower question that brings international couples here: how a prenup interacts with the green card process.
The short answer A prenup is a contract between you and your partner about how you will handle assets and debt. It does not appear on a green card application, and USCIS does not evaluate whether you signed one. The agency evaluates whether your marriage is bona fide, meaning genuine, entered into for reasons other than immigration benefits. A prenup is a normal, lawful contract many couples sign for ordinary reasons. It does not by itself signal anything about the authenticity of a marriage.
There is one thing a prenup cannot reach: the sponsor's support obligation under the Affidavit of Support. That obligation lives in a separate contract, with a different party on the other side. Understanding why those two contracts are independent is the heart of this whole question.
Two different contracts The confusion almost always comes from blurring two agreements that have nothing to do with each other beyond timing.
The first is your prenup. It is signed between you and your partner. It governs how you will divide property and debt if the marriage ends, and it operates under state family law.
The second is the Affidavit of Support, known as Form I-864. This is a contract a sponsor signs promising the U.S. government to financially support a sponsored immigrant so they do not have to rely on certain public benefits. The parties here are the sponsor and the federal government, not the two spouses. According to the USCIS Policy Manual , the Affidavit of Support is a legally enforceable contract.
Because these two contracts have different parties and different purposes, terms you write into one generally cannot rewrite the other. A table makes the separation clearer.

What the Affidavit of Support actually commits you to When a sponsor signs Form I-864, they take on a specific financial promise. According to the USCIS Form I-864 Instructions , the sponsor agrees to maintain the immigrant at an income of at least 125% of the Federal Poverty Guidelines for the household size. (A 100% threshold applies for certain active-duty military sponsors supporting a spouse or child.) If the immigrant later receives certain means-tested public benefits, the agency that paid them can seek repayment from the sponsor.
Here is the part that surprises people most. According to USCIS, divorce does not terminate your obligations under Form I-864 . The promise continues after a marriage ends. The obligation generally ends only in a short list of situations: the immigrant becomes a U.S. citizen, is credited with 40 quarters of work (about ten years), permanently leaves the United States, or either the sponsor or the immigrant dies. It does not run out on a flat ten-year timer; it tracks the 40-quarters rule that USCIS describes.
Why a prenup generally can't waive the I-864 So why can't a couple just write into their prenup that the sponsor's support duty is waived? The answer comes back to who the parties are.
The sponsored immigrant is a third-party beneficiary of the I-864, meaning someone who can enforce a contract they benefit from even though they did not sign it. The contract itself is between the sponsor and the government. A prenup is between the two spouses. Most federal courts that have looked at this have held that spouses cannot sign away, in their private agreement, a support right that flows from the government contract.
In Erler v. Erler , a federal court in California held that a premarital agreement did not waive the duty of support created by Form I-864. The court treated the I-864 as a contract with the government, separate from the prenup between spouses. A federal appeals court reached a related conclusion in Wenfang Liu v. Mund , holding that the sponsor's support duty continued and that the immigrant had no obligation to mitigate by seeking work.
A note on precision here. Most federal courts have ruled this way, and that is the prevailing view, but outcomes can vary by case and by jurisdiction, and a minority view exists. This is a federal, case-specific area, which is one reason it belongs with an immigration attorney rather than a blog post.
What a prenup can still do for international couples None of this means a prenup is pointless when one partner is immigrating. The opposite is often true. A prenup cannot touch the I-864, but it can do everything it normally does, which for international couples can be substantial.
International couples frequently hold assets in more than one country, may be subject to differing national laws, and sometimes need agreements in more than one language. A prenup can set clear terms for separate property, debt, and cross-border assets in the event of divorce. Our deeper guide on prenups for international couples covers the cross-border enforceability, foreign-asset, and translation considerations in detail. For the fundamentals of what a well-drafted agreement should include, the prenup primer walks through the building blocks.
The mental model that keeps this straight: the prenup handles your agreement with each other, and the Affidavit of Support handles a separate promise to the government. One is about how you and your partner divide things; the other is about a federal support obligation that stands on its own.
Frequently Asked Questions Does having a prenup hurt my green card application? No. USCIS does not deny marriage-based green cards because a couple has a prenup. The agency evaluates whether the marriage is genuine, not whether the couple signed a prenuptial agreement. A prenup is a normal, lawful contract many couples sign, and it does not by itself signal anything negative about the marriage.
Can a prenup cancel the Affidavit of Support obligation? Generally no. The Affidavit of Support (Form I-864) is a contract between the sponsor and the U.S. government, and most federal courts have held that a prenup between the spouses cannot waive the immigrant's right to support under it. The two contracts are separate, with different parties.
Does divorce end the sponsor's support obligation? No. According to USCIS, divorce does not terminate your obligations under Form I-864. The obligation generally ends only when the immigrant becomes a U.S. citizen, is credited with 40 quarters of work (about ten years), leaves the U.S. permanently, dies, or the sponsor dies.
What does the sponsor promise on Form I-864? By signing Form I-864, a sponsor agrees to maintain the immigrant at an income of at least 125% of the Federal Poverty Guidelines for the household size, per USCIS. If the immigrant receives certain means-tested public benefits, the agency that paid them can seek repayment from the sponsor.
Should we still get a prenup if one of us is immigrating? Many international couples do. A prenup cannot waive the Affidavit of Support, but it can still set clear terms for separate property, debt, and cross-border assets in the event of divorce. It handles your agreement with each other; the I-864 handles a separate promise to the government.
Do we have to tell USCIS we have a prenup? There is generally no requirement to volunteer a prenup. But if a USCIS officer asks about one at the interview, it should be disclosed honestly; concealing it can create problems. This is a question for an immigration attorney about your specific case.
