K-1 Visa Income Requirements: I-134, I-864, and Co-Sponsors Explained

Financial sponsorship is one of the most common reasons K-1 petitions get delayed or denied at the consular stage — and the most misunderstood part is that two different forms are required at two different stages, with different income standards for each.

Here's what you need to know.

Two Stages, Two Forms

The K-1 process involves two separate financial sponsorship requirements:

1. At the consular interview: Form I-134 (Declaration of Financial Support)
2. After marriage, during Adjustment of Status: Form I-864 (Affidavit of Support Under Section 213A of the INA)

They are not interchangeable. Using the wrong form at the wrong stage is an administrative error that can delay your case.

Form I-134 at the Consular Stage

Form I-134 is the lighter of the two documents. The consular officer uses it to determine whether the beneficiary is likely to become a public charge. The income threshold is generally guided by the HHS Poverty Guidelines — consular posts typically look for income at or above 100% to 125% of the poverty line for the sponsor's household size.

Your I-134 must be supported by:

• Recent federal tax returns (Form 1040 and W-2s)
• A bank statement showing account history from a banking official
• A letter from your employer confirming your salary and permanent employment status

The I-134 is evaluated at the consulate's discretion. It is not a legally enforceable contract the way the I-864 is.

Form I-864 at the Adjustment of Status Stage

The I-864 is far more consequential. It is a legally enforceable contract between you and the U.S. government. By signing it, you commit to maintaining the immigrant's income at or above 125% of the Federal Poverty Guidelines until they become a U.S. citizen, work 40 qualifying quarters, depart permanently, or die.

For 2026, the income thresholds under the 125% standard are:

Active-duty military personnel petitioning for a spouse or fiancé(e) only need to meet 100% of the poverty guidelines — a household of two requires $21,640.

K-1 Visa Income Requirements in Practice

When calculating your household size, include yourself, your fiancé(e), any dependents you're already financially responsible for, and anyone else you've previously filed an I-864 for who is now a permanent resident.

If your income is slightly below the threshold, you have two legitimate options:

Option 1: Count assets. Certain liquid assets — cash, savings accounts, stocks, real estate equity — can supplement your income. USCIS applies a formula: for the I-864, assets must be worth five times the gap between your income and the threshold (three times for a spouse or child of a U.S. citizen).

Option 2: Use a joint sponsor (co-sponsor). A joint sponsor is a separate individual — a family member, friend, or anyone willing — who files their own independent I-864 alongside yours. The joint sponsor must independently meet the 125% income threshold for their own household, which includes the immigrant. The joint sponsor takes on the same legally enforceable obligation as the primary petitioner.

K-1 Co-Sponsor Requirements

To qualify as a joint sponsor, a person must:

• Be a U.S. citizen or lawful permanent resident
• Be at least 18 years old
• Be domiciled in the United States
• Meet the 125% income threshold independently (their income is not combined with the petitioner's — it must be sufficient on its own)

The co-sponsor cannot submit a weaker form of financial evidence hoping to combine it with yours. Each I-864 is evaluated independently. If your income is $5,000 short of the threshold, your co-sponsor needs to clear the entire 125% bar for their household size on their own.

What Happens If the Income Standard Isn't Met

At the consular stage, an officer who finds the I-134 insufficient will typically issue a blue slip requesting additional financial documentation, or in severe cases, deny the visa on public charge grounds. At the AOS stage, a deficient I-864 will result in a Request for Evidence, adding months to processing time.

This is one of the most preventable problems in the K-1 process — the thresholds are published, and gathering tax returns and employer letters is straightforward. The errors happen when petitioners submit an I-864 without understanding which household members to count, or when they assume their assets can substitute for income without correctly applying the formula.

The US K-1 Fiancé Visa Guide includes a complete financial sponsorship checklist covering both the I-134 and I-864, with the exact documentation list for each stage.

Common Mistakes to Avoid

Submitting an I-864 at the consulate. The I-864 is for domestic AOS only. The consulate requires the I-134.

Not including the immigrant in your household size. When calculating the I-864 threshold, your household size includes your fiancé(e) who will be immigrating.

Assuming the same co-sponsor works for both stages. The I-134 co-sponsor and I-864 joint sponsor must be re-confirmed at each stage. A person who helped at the consular stage should re-submit an updated I-864 for the AOS filing.

Using outdated poverty guideline numbers. HHS updates these annually. Always use the most current figures — for 2026, the household-of-two threshold under the 125% standard is $27,050.

Understanding these thresholds before you file prevents the most common financial sponsorship delays. If your income is close to the line, start documenting assets and identifying a potential co-sponsor early — you don't want to be scrambling for this after your petition has already been pending for months.
