In a Nutshell

To prepare a K-1 fiancé(e) visa application for U.S. Citizenship and Immigration Services (USCIS), you must complete the required forms, gather supporting documents, and pay fees. It’s not mandatory to include a cover letter in your application packet, but doing so can help keep your application materials organized and make sure you don’t miss any required documents. You can also use the cover letter to highlight anything you want USCIS to know about your visa application. This article explains what a K-1 fiancé visa cover letter is and the elements it should include. There’s also a template you can use to write your own.

What Is a Form I-129F Cover Letter?

You’ll need to file Form I-129F: Petition for Alien Fiancé if you are a U.S. citizen who wants your foreign partner to receive a K-1 visa. Though it’s not required, writing a cover letter to supplement this form can be helpful for USCIS. A cover letter is a document that outlines your application contents and addresses any unusual circumstances you’d like to flag for your application readers.

A cover letter can give your USCIS officer a useful overview of you and your partner’s case. You can also use your cover letter as a personal checklist to make sure you’ve included all necessary documents in your package.

Is a Cover Letter Required for My Form I-129F Application?

USCIS does not require a cover letter for your Form I-129F petition package. However, it’s often beneficial for applicants to include cover letters. A cover letter can help your USCIS officer better understand and evaluate your overall application.

If there is anything unclear about you and your foreign fiancé’s relationship, a cover letter gives you the opportunity to address these concerns upfront. Remember that USCIS only wants to distribute K-1 visas to couples in genuine relationships. If there is anything unusual about how your relationship started or progressed, you may wish to address it with a disclaimer in your cover letter. 

If you call attention to any unusual circumstances in your cover letter, you’ll be able to explain your side of the story in greater detail. By giving USCIS greater clarity on your case, you can make it easier for the USCIS officer to process your application.

What Should My K-1 Fiancé(e) Visa Cover Letter Include?

You should begin your Form I-129F cover letter with a heading and greeting. Your heading should provide USCIS officials with your mailing address, your name, and your foreign partner’s name. Your introduction should then explain your reasons for writing this cover letter. Use your introduction to give USCIS a basic overview of your relationship and tell them you are seeking a K-1 visa for your fiancé.

Checklist of Information To Include in Your K-1 Fiancé Visa Cover Letter

USCIS will find it most helpful if you include the following information in your cover letter:

  • Your contact information

  • The USCIS address to which you’re sending this letter

  • Your full name as the petitioner

  • Your fiancé’s full name as the beneficiary

  • A note stating which form and visa you are filing an application for

  • A list of all the supporting documents you’ve included in your package, in bullet points:

    • You must include evidence of your U.S. citizenship, such as your birth certificate, copy of your naturalization certificate, Form FS-240, an unexpired U.S. passport, or an original statement from a U.S. consular officer verifying that you are a citizen with a valid passport.

    • You’ll also need evidence that you and your fiancé have legally terminated any previous marriages. For example, you may need to include divorce decrees, annulment orders, or a former spouse’s death certificate.

    • You’ll need one color passport-style photograph of yourself.

    • You’ll also need one color passport-style photograph of your fiancé taken within 30 days of filing.

    • If you or your fiancé have ever changed your name, you’ll need to provide evidence of this legal name change.

    • You’ll need evidence that you and your fiancé intend to marry within 90 days of their admission into the United States.

    • Finally, you’ll also need evidence that you and your fiancé have met in person within two years of filing for this visa. Alternatively, you may submit evidence that an in-person meeting would cause extreme hardship or violate strict traditions of your fiancé’s foreign culture.

  • Your signature and the date

Lastly, you should thank USCIS for their time and conclude your letter. Remember that this cover letter should be the first part of your application package that USCIS sees. You should place it at the top of your overall package before mailing it out to the appropriate USCIS office.

Tips for Writing Your K-1 Fiancé Visa Cover Letter

Be sure to write your letter clearly and concisely. Remember that your cover letter is only a summary of your application contents, so you won’t need to write too many details in this letter. You should also use bullet points when listing your included application materials. Using bullet points will help your USCIS officer more easily understand your application throughout the visa process.

Within your letter, you’ll want to mention that the documents you’ve provided throughout your package are accurate and unaltered original documents or photocopies. If you’ve included any certified translations in your package, be sure to mention this too.
