K1 AOS Payment Amount Calculator

The K1 adjustment-of-status (AOS) payment amount depends on the applicant’s filing category, age, and any applicable fee exemption or special rule; there is no single amount that applies to every K-1 entrant. This calculator estimates the basic USCIS government filing fees for a K-1 entrant applying for adjustment of status, using the inputs below, and does not include optional services or case-specific charges.

Formula

This calculator uses a fixed illustrative base filing amount of $1,440 for Form I-485, plus any separately entered biometrics charge and optional travel-document charge:

• Estimated AOS filing payment = $1,440 + biometrics fee
• Estimated payment including travel document = estimated AOS filing payment + travel-document fee

Here, age is the applicant’s age in years; biom is a separately applicable biometrics fee in U.S. dollars; and travel is an optional travel-document fee in U.S. dollars. The age input is included to prompt a check of eligibility for a reduced fee or other age-based rule; this simple calculator does not automatically apply age-based exceptions. The displayed base amount is an illustrative figure, not a live fee lookup. Confirm the fee schedule in effect on the day of filing with USCIS before paying.

Worked Example

With the default inputs—age 30, biometrics fee $0, and optional travel-document fee $0—the calculation is:

1. Base AOS amount: $1,440 + $0 = $1,440.00.
2. Amount including optional travel document: $1,440.00 + $0 = $1,440.00.

The result is an estimate based on the calculator’s stated assumptions. Actual required payment can differ if USCIS has changed its fee schedule or the applicant’s circumstances trigger a different fee or exemption.

Assumptions

• The example uses a fixed $1,440 base amount for the Form I-485 filing fee; it is not updated automatically.
• Payments are treated as one-time filing charges, not loan installments or recurring payments.
• No interest or compounding applies.
• The estimate excludes legal assistance, mailing or delivery charges, medical examination costs, translations, and any other third-party expenses.
• It does not decide eligibility for a reduced fee, fee waiver, exemption, or related immigration benefit.

What K-1 AOS Means

A K-1 visa is for a foreign-citizen fiancé(e) of a U.S. citizen to enter the United States for the purpose of marrying that petitioner. After the marriage, the K-1 entrant may apply for adjustment of status (AOS) to become a lawful permanent resident. The main application is Form I-485, Application to Register Permanent Residence or Adjust Status.

“K-1 AOS payment” usually means the government filing fee for the adjustment application. It is separate from the costs paid earlier in the visa process and from optional applications filed alongside the I-485. The specific payment due is not determined just by the words “K-1 AOS”: current fee rules, age, filing circumstances, and the forms submitted together can matter.

What May Change the Amount

USCIS fee schedules can change, so a figure found in an older forum post, checklist, or article may no longer apply. Check the official USCIS fee information and the instructions for each form immediately before filing. Follow the payment method and amount specified there; an incorrect fee can cause a filing to be rejected or delayed.

Age is relevant because some fee schedules provide different treatment for certain applicants based on age or other circumstances. This calculator does not infer an exception from age: it leaves the displayed base amount unchanged. Likewise, it cannot tell whether a fee waiver is available or whether an applicant qualifies. Do not subtract a fee or assume a waiver applies without checking the current official instructions for that applicant’s exact filing.

There may also be charges for separate forms or services. For example, an applicant may consider applying for employment authorization or advance parole, which concerns travel while an adjustment application is pending. Whether a separate fee applies, or whether a form is included or exempt under the current rules, depends on the governing fee schedule and filing details. The optional travel input is for estimation only; it does not establish that a travel document is necessary or that a particular charge is due.

How to Use the Calculator

• Enter the applicant’s age to remind yourself to check age-related fee rules in the current official instructions.
• Enter a biometrics amount only if the current instructions show that it is separately due in the applicant’s case. Enter zero otherwise.
• Enter an optional travel-document amount only if filing that application and the current schedule requires a separate payment. Enter zero if not applicable.
• Compare the estimate with the official fee total and payment instructions for every form in the package before submitting.

For instance, if the applicable official instructions confirm a separate $85 charge, entering 85 in the biometrics field adds $85 to the base estimate. That example demonstrates the arithmetic only; it does not assert that $85 is currently required. Use the actual amount shown by official, current instructions.

Common Payment Mistakes and Limits

A frequent misconception is that every K-1 entrant pays one identical “AOS fee.” The required amount can depend on the fee schedule in force and facts specific to the application. Another common mistake is adding or omitting a fee based on an old application guide. The calculator cannot verify the current price, the applicant’s eligibility, the correct filing package, or the proper payment method.

Keep the following distinctions in mind:

• The calculator estimates government filing charges, not the total cost of the immigration process.
• A medical exam, legal help, translations, and document delivery may create costs that are not included here.
• Filing an optional form can affect the total, but the applicable fee must be checked separately.
• A fee exemption or waiver is not automatic just because an applicant believes they meet a condition; confirm the official requirements.
• Use the current USCIS form instructions and fee schedule rather than relying on a calculator’s example amount.

Because this is an estimate tool rather than an eligibility review, questions about an individual case should be checked against USCIS instructions or addressed with a qualified immigration professional. Do not send a payment solely on the basis of the calculator’s default.

Frequently Asked Questions

How much is the K-1 AOS fee?
The amount depends on the current USCIS fee schedule and the applicant’s circumstances. This page uses $1,440 as an illustrative base amount, not a guaranteed current fee; verify the exact amount with USCIS before filing.

Does the K-1 AOS fee include biometrics?
Whether biometrics has a separate charge depends on the applicable fee schedule and case. Check the current instructions, then enter a separate amount only if it is required.

Do I pay extra for a work permit or travel document?
That depends on the forms being filed and the current fee rules. Check the instructions for each form; this calculator does not determine whether a charge applies.

Can a K-1 adjustment applicant get a fee waiver?
Some applicants may have a fee exemption or waiver route under applicable instructions, but this calculator cannot assess eligibility. Review the official criteria and documentation requirements.

Does the K-1 AOS payment include the medical exam?
No. This estimate covers only the modeled government filing charges. A medical examination and other third-party expenses are not included.

This is estimate arithmetic for education, not financial or immigration advice; the applicable USCIS instructions and payment disclosure give the exact figures.
