K-1 Visa Form I-134 in 2026: Income Requirements, Who Files It, and Common Mistakes

K-1 Visa Form I-134 in 2026: Income Requirements, Who Files It, and Common Mistakes

If you are preparing for a K-1 fiance visa interview, one of the most important financial documents in the case is Form I-134, Declaration of Financial Support.

The short answer is this: in 2026, a consular officer may request Form I-134 from the U.S. citizen petitioner in a K-1 case to evaluate whether the applicant is likely to become a public charge. The financial benchmark tied to Form I-134 is generally 100% of the federal poverty guideline, not the 125% rule that applies to Form I-864 after marriage and adjustment of status. USCIS also says a separate Form I-134 is required for each beneficiary.

That sounds straightforward, but this part of the K-1 process still causes confusion. Couples often mix up Form I-134 and Form I-864, assume the wrong income threshold applies, or show up to the interview with weak financial evidence.

Form I-134 is the financial-support form commonly used at the K-1 visa interview stage.

The purpose is not to complete the green card sponsorship requirement yet. Instead, it helps the consular officer evaluate whether the foreign national fiance applicant is likely to become a public charge during the temporary K-1 stage.

That distinction matters because K-1 cases involve two different financial-support stages:

• before entry and marriage: the visa interview may require Form I-134, and
• after marriage in the United States: the adjustment-of-status package requires Form I-864.

A lot of avoidable mistakes happen because couples prepare for the second step while still in the first one.

In a standard K-1 fiance visa case, the U.S. citizen petitioner is the person who completes and signs Form I-134.

The foreign national fiance beneficiary does not usually sign the sponsor's I-134. The financial-support declaration is made by the sponsor.

USCIS also states that:

• you must file a separate Form I-134 for each beneficiary, and
• the sponsor must sign the form using their full name.

That means if a case includes a K-2 child, you should not assume one I-134 automatically covers everyone. The safer rule is to prepare the financial-support paperwork carefully for each beneficiary the government expects to review.

Another useful practical point: Form I-134 does not need to be notarized. USCIS says signing it is already under penalty of perjury.

This is one of the biggest K-1 financial-support mistakes.

For a K-1 visa interview using Form I-134, the relevant benchmark is generally 100% of the federal poverty guideline.

The 125% rule is tied to Form I-864, which comes later when the couple marries and files for adjustment of status.

The Department of State says those are not the same income rules. In plain English:

• K-1 visa stage / Form I-134 = generally 100% benchmark
• green card stage / Form I-864 = generally 125% benchmark

This is why some couples panic unnecessarily by applying the higher number too early, while others make the opposite mistake and underestimate what the later green card filing will require.

For the 48 contiguous states and the District of Columbia, the 2026 federal poverty guideline examples are:

• household size 2: $21,640
• household size 3: $27,320
• household size 4: $33,000

Those are useful examples for many K-1 couples, but the real analysis still depends on the sponsor's actual household size and the people being financially supported.

Also remember:

• Alaska and Hawaii use higher poverty-guideline numbers, and
• consular officers may look at the total financial picture, not just one line on one tax document.

So the smart approach is not just to hit the number on paper. It is to show a stable and well-documented support picture.

---

The exact supporting documents can vary by U.S. embassy or consulate, but the goal is always the same: show that the U.S. citizen sponsor has sufficient income or financial resources.

In practice, strong K-1 interview preparation usually includes current and organized financial proof such as:

• a completed and signed Form I-134,
• recent tax documentation,
• evidence of current employment and current income, and
• supporting proof of financial resources if income alone is tight.

The key is consistency.

If the sponsor's income changed recently, the tax return alone may not tell the whole story. If the sponsor changed jobs, became self-employed, or earns variable income, the couple should think carefully about how the financial record will look to a consular officer reviewing the case quickly.

Mistake 1: Using the wrong form at the wrong stage

Some couples prepare Form I-864 for the visa interview stage. That is usually the wrong approach. The I-864 comes later with the green card filing after marriage.

Mistake 2: Applying the 125% rule too early

For K-1 interview purposes, the Department of State says the 100% guideline is the relevant benchmark for Form I-134, not 125%.

Mistake 3: Assuming one I-134 covers every beneficiary

USCIS says a separate Form I-134 is required for each beneficiary.

Mistake 4: Sending weak or outdated financial proof

A sponsor may have enough income in reality, but if the evidence is old, incomplete, or internally inconsistent, the case can still face delays or additional questions.

Mistake 5: Forgetting that the consulate may have post-specific instructions

The general federal rules matter, but each embassy or consulate may also give its own document instructions for K visa interviews.

Mistake 6: Forgetting to sign the form

USCIS says it will reject an unsigned Form I-134.

Once the K-1 beneficiary enters the United States and the couple marries, the financial-support analysis changes.

At that stage, the couple typically moves into the adjustment-of-status process, and the U.S. citizen spouse will generally need to file Form I-864 with USCIS.

That later stage is where the 125% poverty-guideline rule usually becomes important.

So a clean way to think about the timeline is:

1. K-1 visa interview abroad → usually Form I-134 issues
2. Marriage in the United States → move to adjustment of status
3. Green card filing → generally Form I-864 issues

Keeping those steps separate can prevent a lot of confusion.

Who files Form I-134 for a K-1 visa in 2026?

Usually the U.S. citizen petitioner completes and signs the form for the K-1 visa case.

Is Form I-134 required in every K-1 case?

The Department of State says the consular officer may request Form I-134. In practice, applicants should prepare carefully for that possibility and follow the specific instructions from the embassy or consulate handling the interview.

Is the K-1 income requirement 100% or 125% of the poverty guideline?

For Form I-134 at the K-1 visa stage, the Department of State says the relevant benchmark is 100% of the federal poverty guideline, not 125%.

Does Form I-134 need to be notarized?

No. USCIS says the sponsor signs Form I-134 under penalty of perjury, so notarization is not required.

Do I need a separate I-134 for a K-2 child?

USCIS says you must file a separate Form I-134 for each beneficiary.

Is Form I-134 the same as Form I-864?

No. Form I-134 is tied to temporary financial-support review at the visa stage, while Form I-864 is the affidavit of support generally used later for the green card process after marriage.

---

In 2026, the safest way to approach K-1 visa Form I-134 is to remember three core rules: the U.S. citizen petitioner usually files it, the K-1 stage generally uses the 100% poverty-guideline benchmark, and the later green card stage is a separate I-864 analysis.

A K-1 case can be delayed by something as simple as bringing the wrong financial form, using the wrong income threshold, or showing up with weak documentation.

At Alaz Law, we help couples prepare K-1 cases with the kind of organized, high-credibility strategy that reduces avoidable interview problems and keeps the case moving.

K-1 visa financial-support issues can become more complicated when income is irregular, household size is disputed, prior sponsorship obligations exist, the embassy has post-specific document rules, or the case later moves into adjustment-of-status strategy.
