What Documents Are Required for Form I-130? Complete Guide

Filing Form I-130, Petition for Alien Relative, is one of the first and most important steps in helping a family member immigrate to the United States. While completing the form itself is important, many applicants are surprised to learn that the supporting documents are often what determine whether the petition moves smoothly or gets delayed.

USCIS uses these documents to confirm two things:

1. The petitioner is eligible to sponsor a relative
2. The claimed family relationship is genuine and properly documented

Missing, incorrect, or weak evidence can lead to Requests for Evidence (RFEs), delays, or even denials. This guide explains the documents USCIS commonly requires for Form I-130, how those requirements change based on the relationship type, and how to avoid common mistakes during the process.

Quick Answer: Documents Required for Form I-130

Most Form I-130 petitions require:

• Proof of U.S. citizenship or permanent resident status
• Proof of the family relationship
• Government-issued identity documents
• Passport-style photos (in some cases)
• Certified English translations for non-English documents
• Additional relationship-specific evidence

The exact documents depend on whether you are filing for a spouse, parent, child, or sibling.

Relationship Type	Main Documents Required
Spouse	Marriage certificate, proof of bona fide marriage, divorce records (if applicable)
Child	Birth certificate, adoption or custody records (if applicable)
Parent	Petitioner’s birth certificate showing parent names
Sibling	Birth certificates showing at least one shared parent
All Applicants	Proof of status, identity documents, translations (if needed)

Why Supporting Documents Matter for Form I-130

USCIS officers use your supporting documents to verify that your family relationship is real and that you meet the eligibility requirements for Form I-130. In many cases, the documents you submit are the primary evidence USCIS reviews when deciding on your petition.

If important documents are missing, unclear, or inconsistent, USCIS may delay your case or ask for additional evidence.

Common outcomes of incomplete documentation include:

• Request for Evidence (RFE): USCIS pauses your case and asks for missing or additional documents. Responding to an RFE can add several months to your processing time. Learn more about how to respond to RFE from our guide.
• Notice of Intent to Deny (NOID): USCIS believes there may be a problem with eligibility or supporting evidence and allows you to respond before making a final decision.
• Petition denial: If USCIS cannot verify eligibility or the claimed relationship, the petition may be denied, requiring you to refile and pay new filing fees.

In recent years, USCIS has increased scrutiny of family-based immigration petitions, especially marriage-based cases. Providing complete, organized, and accurate documents from the beginning can help reduce delays and strengthen your petition.

Strong documentation helps USCIS process the case more efficiently and reduces the chances of delays.

Core Documents Required for All Form I-130 Petitions

Although requirements vary by case type, some documents are commonly required in almost every Form I-130 petition.

Proof of U.S. Citizenship or Permanent Resident Status

The petitioner must prove they are eligible to sponsor a relative.

If You Are a U.S. Citizen

You may submit copies of:

• U.S. passport – Valid, unexpired. A copy of the biographical page is sufficient
• U.S. birth certificate – Must be issued by the civil authority (state, county, or municipality) and show a file date
• Naturalization certificate – Issued by USCIS upon naturalization
• Certificate of citizenship – Issued to those who derived citizenship through a parent
• Consular Report of Birth Abroad – Only if one was obtained; issued to U.S. citizens born outside the U.S. to citizen parents
• U.S. military ID card with photo – Accepted in certain overseas filing situations

If You Are a Green Card Holder

You typically submit:

• Copy of Permanent Resident Card (front and back)

Petitioner Status	Common Evidence
U.S. Citizen	Passport, birth certificate, naturalization certificate, citizenship certificate
Permanent Resident	Green card copy

USCIS generally accepts photocopies unless original documents are specifically requested later.

Government-Issued Identity Documents

USCIS may also require identity documents for the petitioner and beneficiary.

Common examples include:

• Passport biographic page
• Government-issued photo ID
• Driver’s license (supporting document)

The information on these documents should match the details entered on Form I-130. Differences in names, birth dates, or spellings can create delays or RFEs.

Passport-Style Photos

Passport-style photos may be required depending on how and where the application is filed.

Generally:

• Paper-filed applications are more likely to require photos
• Online filing requirements may vary based on the case type

Photos must follow USCIS specifications, including:

• White background
• Clear image quality
• Correct size and dimensions

Submitting outdated or incorrect photos may slow down processing.

Certified English Translations

Any document submitted in a language other than English must include a complete English translation.

The translation must include:

• Full translation of the document
• Translator certification confirming accuracy

USCIS may reject partial or incomplete translations. This is one of the most common reasons applicants receive RFEs.

Example of Documents Often Requiring Translation

• Foreign birth certificates
• Marriage certificates
• Divorce records
• Adoption documents

Relationship-Specific Documents for Form I-130

The most important supporting evidence depends on the relationship between the petitioner and beneficiary.

Documents Required for a Spouse-Based Form I-130

Petitioning for a spouse is the most common I-130 scenario, and it involves the most extensive documentation of any relationship category. This is because USCIS applies closer review to marriage-based petitions to detect fraudulent “sham marriages” entered into for the sole purpose of obtaining immigration benefits.

Required forms

• Form I-130 (completed and signed by the petitioner)
• Form I-130A (Supplemental Information for Spouse Beneficiary) — required when petitioning for a spouse. If the spouse (beneficiary) is outside the United States, they are not required to sign Form I-130A, but the form must still be completed.

Note: Form G-325A (Biographic Information) is no longer required. Biographic information was incorporated directly into Form I-130 and I-130A beginning with the February 27, 2017, edition of the form.

Required Marriage Documents

Issued by the governmental authority where the marriage was performed. Must have an official file date. A church certificate alone is not acceptable in most cases; you need the civil certificate issued by the municipality or equivalent government body.

Prior marriage termination (if applicable)

If either spouse was previously married, you must submit documents proving all prior marriages were legally terminated:

• Divorce decree(s) — final judgment, not a separation agreement
• Death certificate(s) — if prior spouse is deceased
• Annulment documentation — if prior marriage was annulled

Failure to document prior marriages is a frequent cause of denial. USCIS will not assume a prior marriage ended.

Proof of a Bona Fide Marriage

USCIS wants evidence showing you and your spouse share a real life together.

Examples of strong evidence include:

Strong Evidence	Weaker Evidence
Joint tax returns	Social media screenshots only
Joint lease or mortgage	A few photos together
Shared insurance policies	Chat messages only
Joint bank accounts	Limited communication records
Children’s birth certificates	Unorganized screenshots

Quality matters more than quantity. A few strong documents are often more helpful than hundreds of unrelated pages.

Special considerations for newly married couples

For couples who have recently married and have not yet had time to combine finances, open joint accounts, or establish a shared household, the evidence package will naturally be thinner. In these cases, affidavits from people who know both spouses carry more weight than usual. A detailed cover letter explaining the circumstances of the relationship, courtship timeline, and current living arrangement can also help contextualize the evidence.

Documents Required for Form I-130 for Children

When petitioning for a child, the required documents differ based on the child’s situation: natural child, stepchild, or adopted child. Each scenario has different proof requirements.

For a natural (biological) child

• Child’s birth certificate showing the names of both parents. This is the primary document establishing the parent-child relationship.
• Petitioner’s birth certificate or other status document (to establish the petitioner’s identity and eligibility)
• Marriage certificate of the child’s parents — required if the child was born in wedlock and the petitioner’s name on the birth certificate differs from the name on their status document
• Proof of legal parent-child recognition — if the child was born out of wedlock and the petitioner is the father, proof that the child was legitimated before age 18 may be required under the laws of the child’s home country or the father’s residence

For a stepchild

A stepparent-stepchild relationship qualifies only if the marriage creating the relationship occurred before the child’s 18th birthday.

• Child’s birth certificate
• Marriage certificate of the petitioning stepparent to the child’s biological parent
• Proof that any prior marriages of the petitioning stepparent were legally terminated

For an adopted child

Adoption cases have specific legal requirements. Documents must show:

• The adoption was legally completed before the child turned 16 (or 18 in certain circumstances involving siblings)
• The petitioner has had legal custody of the child for at least two years
• The petitioner has lived with the child for at least two years

Supporting documents include the adoption decree or court order, custody documentation with dates, and evidence of cohabitation such as school records or utility bills showing the shared address.

When a birth certificate is unavailable

If the child’s birth certificate does not exist or cannot be obtained, you must:

1. Submit a statement from the issuing government authority in the child’s home country confirming that the birth certificate is unavailable from that agency.
2. Provide secondary evidence such as baptismal certificates (issued at the time of baptism), school records signed by a parent, prenatal or doctor records, or affidavits from relatives with personal knowledge of the birth.

Documents Required for Form I-130 for Parents

A U.S. citizen who is at least 21 years old can petition for a parent (mother or father). Parents of U.S. citizens are classified as immediate relatives, meaning there is no annual visa cap and no waiting period for a visa number to become available after the I-130 is approved.

Note: Lawful permanent residents cannot file Form I-130 for a parent under any circumstances.

Documents required when petitioning for a mother

• Petitioner’s birth certificate showing the mother’s name
• Proof of petitioner’s U.S. citizenship (birth certificate, U.S. passport, or naturalization certificate)
• If the petitioner’s birth certificate shows a different last name than their current name: marriage certificate or legal name change documentation to bridge the gap

Documents required when petitioning for a father

• Petitioner’s birth certificate showing the father’s name
• Parents’ marriage certificate — if petitioner was born in wedlock, to establish the legal paternity relationship
• Additional documents may be required if the child was born outside of marriage.
• Proof of petitioner’s U.S. citizenship

For a stepparent

• Petitioner’s birth certificate
• Marriage certificate showing that the stepparent married the petitioner’s biological parent before the petitioner turned 18
• Proof that prior marriages were legally terminated

Documents Required for Form I-130 for Siblings

U.S. citizens who are at least 21 years old can file Form I-130 for a brother or sister. Sibling petitions fall under the Family Fourth Preference (F4) category — the lowest priority in family-based immigration — and carry the longest processing and visa wait times of any I-130 category.

Lawful permanent residents cannot petition for siblings.

Required documents

• Petitioner’s birth certificate showing the names of both parents
• Beneficiary sibling’s birth certificate showing the same parent(s) — this is how USCIS confirms the sibling relationship
• If siblings share only one parent in common: the birth certificates must clearly establish the shared parent. If one or both parents were married to other people, marriage certificates and/or divorce decrees may be needed to clarify the relationship.
• If names have changed due to marriage, adoption, or legal name change: supporting documents (marriage certificate, court order) must connect current names back to names on the birth certificates
• Proof of petitioner’s U.S. citizenship

Secondary Evidence When Primary Documents Are Unavailable

USCIS understands that vital records — birth certificates, marriage certificates, civil registration documents — are not always available, particularly for applicants from countries with limited record-keeping infrastructure or regions affected by conflict, natural disasters, or bureaucratic gaps.

If a primary document is unavailable, you cannot simply omit it. You must follow a two-step process:

Step 1: Establish unavailability

Submit a statement or certification from the official government authority responsible for issuing the document — such as the vital records office, civil registry, or municipal archive — confirming that the record does not exist, was destroyed, or cannot be located. This is not a statement you write yourself; it must come from the issuing authority.

If the document exists but cannot be obtained in time, a letter explaining the delay and your efforts to obtain the record can accompany a request for additional time.

Step 2: Submit secondary evidence

Once you have established that the primary document is unavailable, you may submit secondary evidence to establish the same facts. Acceptable secondary evidence may include:

For birth records:

• Baptismal certificate (must be from the actual date of baptism, not a recently issued ceremonial certificate)
• School records or report cards registered or signed by a parent
• Prenatal records or doctor’s notes from around the time of birth
• Baby book or family Bible entries recording the birth
• Government-issued identification (Social Security card, national identity card, driver’s license)
• Affidavits from relatives — parents, aunts, uncles, or older siblings — who have personal knowledge of the birth

For marriage records:

• Church records of a religious marriage ceremony
• Cohabitation evidence (shared utility bills, lease agreements, correspondence)
• Affidavits from witnesses present at the marriage

For civil status records in general:

• Newspaper announcements
• Census records
• Hospital or medical records referencing the relevant relationship

USCIS evaluates secondary evidence on a case-by-case basis. The stronger and more varied the secondary evidence, the better. A single affidavit without supporting evidence carries less weight than a combination of a church record, school records, and two family affidavits.

Common Document Mistakes That Can Delay Form I-130

Missing or poorly prepared supporting documents are one of the most common reasons Form I-130 petitions get delayed. USCIS carefully reviews relationship evidence, identity records, and translations to verify eligibility.

Below are some common document-related mistakes applicants make.

Weak Marriage Evidence

For spouse-based petitions, submitting only a marriage certificate and a few photos is usually not enough. USCIS often expects evidence showing the couple shares a real life, such as joint financial records, housing documents, insurance policies, travel records, and photos from different time periods.

Inconsistent Information Across Documents

Names, birth dates, addresses, and marriage details should match across all forms and supporting documents. Even small differences can create confusion and lead to additional review or delays.

Missing English Translations

USCIS requires certified English translations for documents written in another language. Missing or incomplete translations are a common reason applicants receive Requests for Evidence (RFEs).

Sending Incomplete Relationship Documents

Missing divorce records, adoption papers, custody documents, or other supporting evidence may delay processing. USCIS uses these documents to confirm the claimed family relationship. See the latest Form I-130 processing time estimates and common delay factors.

Incomplete RFE Responses

If USCIS requests additional evidence, incomplete responses or missing documents may lead to further delays or denial of the petition.

Do You Need Originals or Copies for Form I-130?

In most cases, USCIS accepts photocopies of supporting documents when filing Form I-130. Original documents should only be submitted if USCIS specifically requests them later.

Applicants should keep copies of everything submitted for their personal records.

Tips for Uploading Form I-130 Documents Online

When uploading documents online, use clear scans and upload complete pages. Organizing files by category and using readable file names can help make your application easier to review.

Avoid blurry images, cropped pages, or incomplete uploads.

Tips for Organizing Your Form I-130 Documents

Organizing your supporting documents properly can make your application easier for USCIS to review and help reduce delays caused by missing or unclear evidence.

Before submitting Form I-130, review your document package carefully and keep related records grouped together.

Helpful Tips

• Arrange documents by category, such as identity documents, relationship evidence, and translations
• Use clear and readable scans for online uploads
• Upload complete pages instead of cropped images
• Make sure names and dates are consistent across all documents
• Include certified English translations for non-English records
• Keep copies of everything submitted to USCIS for your personal records

A well-organized application package can help USCIS review your case more efficiently and reduce the chances of receiving a Request for Evidence (RFE).
