F-2B Sample Cover Letter Template — Sibling-of-Citizen Visa

What an F-2B Cover Letter Actually Does

An F-2B petition reunites a U.S. citizen with their sibling. The cover letter is not the petition itself—Form I-130 is. The letter serves one function: it tells the adjudicating officer what evidence you've included, where each document sits in the packet, and how it proves the sibling relationship and the petitioner's citizenship. USCIS officers process thousands of I-130s. A clear cover letter accelerates review; a confusing one or a missing one doesn't disqualify your petition, but it slows the officer's ability to verify what you filed.

Here's the honest answer: USCIS does not evaluate your relationship by how touching your story sounds. Officers apply 8 U.S.C. § 1151(b)(2)(A)(i), which defines sibling as a child of the same biological or legal parent. The evidence must prove that statutory relationship and the petitioner's citizenship status. Everything else—your family history, why you want to reunite, how long you've been separated—is legally irrelevant to the adjudication. The cover letter exists to organize proof, not to argue.

The Structure USCIS Expects

A compliant F-2B cover letter follows this order:

1. Opening block: petitioner's name, beneficiary's name, USCIS receipt number if this is a follow-up filing, and a subject line: "Form I-130, Petition for Alien Relative — F-2B Sibling of U.S. Citizen."
2. Statement of relationship: one sentence naming the petitioner, the beneficiary, and the qualifying relationship ("Jane Smith, U.S. citizen, petitions on behalf of her brother, Carlos Ramirez").
3. Evidence index: a numbered list of every document in the packet, grouped by what each proves—citizenship, sibling relationship, identity.
4. Signature block: petitioner's signature, printed name, date.

The letter does not need to exceed one page. Officers want the roadmap, not background.

What the Evidence Index Must Cover

The index is the working portion of the letter. Every document in your I-130 packet must appear in the index with a short description. Group items by function:

Proof of petitioner's U.S. citizenship:

• U.S. birth certificate, naturalization certificate, or U.S. passport (biographical page and any pages showing extensions or amendments)

Proof of sibling relationship:

• Petitioner's birth certificate listing both parents
• Beneficiary's birth certificate listing at least one parent in common with the petitioner
• If the relationship is through adoption or a legal name change, the adoption decree or court order establishing legal parentage
• If a parent's name differs between documents (due to marriage, divorce, or transliteration), civil records connecting the name variations—marriage certificate, divorce decree, or an affidavit explaining the discrepancy with supporting documentation

Proof of identity:

• Passport-style photographs of petitioner and beneficiary, annotated on the back
• Government-issued identification for both parties

Supporting civil documents (if applicable):

• Marriage certificates if either party's current name reflects a married name
• Death certificates if a shared parent is deceased and you are submitting their birth certificate or other records as part of the chain of evidence

Every indexed item should appear in the packet in the same order the index lists it. Officers work linearly; if the letter says birth certificate on page 3 and the document appears on page 7, the discrepancy costs time.

Re: Form I-130, Petition for Alien Relative — F-2B Sibling of U.S. Citizen
Petitioner: Jane Marie Smith (U.S. Citizen)
Beneficiary: Carlos Alberto Ramirez (Sibling)

Dear USCIS Officer,

I, Jane Marie Smith, a U.S. citizen, submit this Form I-130 petition on behalf of my brother, Carlos Alberto Ramirez, under the F-2B sibling-of-citizen category. This letter serves as an index to the supporting evidence included in this petition.

Evidence Submitted:

1. Form I-130, Petition for Alien Relative, completed and signed
2. Petitioner's U.S. Citizenship:

• Copy of petitioner's U.S. passport (biographical page), issued February 2024, valid through February 2034

3. Proof of Sibling Relationship:

• Certified copy of petitioner's birth certificate (California, issued 1985), listing father Roberto Ramirez and mother Maria Lopez Ramirez
• Certified copy of beneficiary's birth certificate (Mexico, issued 1990), listing father Roberto Ramirez and mother Maria Lopez Ramirez

4. Proof of Identity:

• Two passport-style photographs of petitioner, name and date printed on reverse
• Two passport-style photographs of beneficiary, name and date printed on reverse
• Copy of petitioner's California driver's license
• Copy of beneficiary's Mexican voter identification card (INE)

5. Filing Fee:

• Check for the Form I-130 filing fee (confirm current amount at uscis.gov/i-130 before submitting)

All birth certificates are accompanied by certified English translations as required. The documents establish that the petitioner and beneficiary share both biological parents, Roberto Ramirez and Maria Lopez Ramirez, satisfying the statutory definition of sibling under INA § 201(b)(2)(A)(i).

Thank you for your consideration of this petition.

Respectfully submitted,

Jane Marie Smith

Common Errors and How to Avoid Them

What If My Sibling and I Share Only One Parent?

The F-2B category covers half-siblings. A sibling relationship under the Immigration and Nationality Act exists when two individuals share at least one biological or adoptive parent. If you and your sibling share only your mother or only your father, you still qualify.

Your evidence must prove the shared parentage. Submit both birth certificates, each listing the common parent by name. If the parent's name appears differently on the two certificates—due to marriage, divorce, or transliteration from a non-English name—submit the civil record explaining the variation. A marriage certificate connecting Maria Lopez to Maria Lopez Ramirez, for example, resolves the discrepancy. If no civil record exists, an affidavit from the parent or a sibling who can attest to the identity may supplement the file, but USCIS prefers official records.

The cover letter notes the shared parent explicitly: "The petitioner and beneficiary share a common mother, Maria Lopez Ramirez, as shown on the enclosed birth certificates." This removes ambiguity.

What If One Parent's Name Is Spelled Differently on Each Birth Certificate?

Name variations across civil documents are common, especially when records originate in different countries or were issued decades apart. Differences in spelling, use of maiden versus married names, inclusion or omission of middle names, and transliteration from non-Latin scripts all appear in I-130 filings.

USCIS does not automatically reject a petition because of a name discrepancy, but the officer must be able to confirm that the two names refer to the same person. Your evidence should make that confirmation straightforward. Include one or more of the following:

• The parent's marriage certificate, if the name changed upon marriage
• A divorce decree, if the parent reverted to a prior surname
• A legal name-change order, if the parent formally changed their name through a court
• The parent's passport or national identity document showing both name forms
• An affidavit from the parent explaining the discrepancy, supported by a copy of their identification

In the cover letter, acknowledge the variation directly: "The beneficiary's birth certificate lists the mother as Maria Lopez; the petitioner's birth certificate lists her as Maria Lopez de Ramirez. The enclosed marriage certificate, issued by [authority] on [date], confirms these names refer to the same individual." Officers process cases faster when you address the issue proactively.

What If the Birth Certificate Is Unavailable?

Some countries do not issue birth certificates, or the certificate was lost and the issuing authority cannot provide a replacement. USCIS permits secondary evidence when the primary document is genuinely unavailable.

Before submitting secondary evidence, request a certificate of non-availability from the civil registry in the jurisdiction where the birth occurred. This is an official statement that the record does not exist or cannot be produced. The certificate of non-availability itself is evidence.

Secondary evidence for birth may include:

• Church baptismal certificate issued shortly after birth, showing parents' names
• Hospital birth record
• School records created near the time of birth
• Census records listing the individual as a child in the household
• Affidavits from individuals with personal knowledge of the birth—parents, older siblings, or other relatives—stating the date, place, and parentage

If you submit affidavits, provide at least two from different affiants. Each affidavit must be notarized or given under oath, and the affiant should explain how they know the facts (e.g., "I am the mother of both the petitioner and beneficiary and was present at both births").

In the cover letter: "The beneficiary's birth certificate is unavailable. A certificate of non-availability from the Jalisco Civil Registry is included. Secondary evidence of birth and parentage is provided: baptismal certificate dated [date], hospital record dated [date], and affidavits from [names]."

Translation and Certification Requirements

Every document not in English must be accompanied by a full English translation. The translator must certify in writing that they are competent to translate from the source language to English and that the translation is complete and accurate. The certification must include the translator's name, signature, and date. A translator does not need formal credentials, but they must be fluent in both languages. USCIS does not accept machine translations, and the petitioner or beneficiary cannot translate their own documents.

Civil documents issued by foreign governments should be certified copies, not photocopies. Many countries issue certified or apostilled copies of birth, marriage, and death certificates. If a certified copy is unavailable, submit the best available copy and explain in the cover letter: "The enclosed birth certificate is a photocopy; certified copies are not available from [issuing authority]. A certificate of non-availability is included."

Do Not Include These in an F-2B Cover Letter

The following do not belong in the letter or the petition packet:

• Explanations of why you want to bring your sibling to the United States
• Descriptions of your sibling's character, job history, or contributions to their community
• Statements about hardship the separation has caused
• Financial documents unless USCIS specifically requested them (the I-130 does not require proof of financial support—that comes later, at the visa stage, via Form I-864)
• Photographs of family gatherings, unless they are the two required passport-style photos
• Letters of recommendation or reference letters

USCIS evaluates the I-130 on two questions: Is the petitioner a U.S. citizen? Is the beneficiary the petitioner's sibling? The answer to both must be yes, proven by civil documents. Everything else is noise.

After You File — What the Cover Letter Does Not Control

The cover letter does not influence processing time. F-2B petitions are subject to the State Department's visa bulletin, and the wait for a priority date to become current can span years, depending on the beneficiary's country of birth. As of 2026, consult the monthly visa bulletin at travel.state.gov for current priority date movement—this changes every month and varies significantly by country.

The letter also does not prevent a Request for Evidence (RFE). If USCIS finds the initial submission incomplete or unclear, the agency issues an RFE asking for additional proof. A well-organized cover letter reduces the likelihood of an RFE, but it does not eliminate the possibility. Respond to any RFE promptly and completely—failure to respond within the deadline results in denial.

Approval of the I-130 does not grant your sibling status or work authorization. It establishes the relationship and places the beneficiary in the queue. The beneficiary becomes eligible to apply for an immigrant visa or adjust status only when the priority date becomes current, a process governed by per-country visa limits.

How the Law Offices of Peter D. Chu Approaches F-2B Filings

At the Law Offices of Peter D. Chu, every I-130 petition begins with a documents audit. Assembling the cover letter is part of the preparation process—it forces a review of what you have, what you're missing, and whether the evidence chain is complete. Gaps surface during the index draft, not after mailing.

For sibling petitions involving foreign civil records, name discrepancies, or missing documents, the firm verifies what secondary evidence will satisfy USCIS before advising you to file. A consultation reviews your specific documents—your sibling's birth certificate, your own citizenship proof, any complications in the civil record—and maps the path from filing through approval and consular processing. The $250 consultation fee is confirmed at peterchu.com, and you can call (858) 268-8823 or visit the office at 4615 Convoy St, San Diego, CA 92111 during business hours (Monday–Friday, 8:30 AM – 5:30 PM).

Final Checklist Before You Mail

Before sealing the envelope:

• Form I-130 completed, signed, and dated by the petitioner
• Filing fee check or money order enclosed (verify the current fee at uscis.gov/i-130—fees change periodically)
• Cover letter signed and dated
• Every document listed in the cover letter index is in the packet, in the same order
• All non-English documents accompanied by certified translations with translator certifications
• Two passport-style photos of petitioner and beneficiary, annotated on reverse
• Copies, not originals, of identity documents (keep originals; submit photocopies unless USCIS specifically requests originals)
• Packet mailed to the correct USCIS lockbox (the address depends on where the petitioner lives—confirm the current filing address on the I-130 instructions page before mailing)

Keep a complete copy of everything you submit. If USCIS issues an RFE or loses part of the file, you will need to reproduce documents.
