Documents you'll need for I-130
The four document categories
A Form I-130 package is built from four distinct categories of documents. Knowing the categories first makes the long checklists easier to organize, because almost every document USCIS asks for falls into one of them [Tier 1: USCIS.gov Form I-130 page, https://www.uscis.gov/i-130].
- Petitioner status and identity — evidence that the person filing is a US citizen or lawful permanent resident, plus proof of who they are.
- Beneficiary identity — evidence of who the family member is, usually a passport and a birth certificate.
- Relationship evidence — documents that show the qualifying family relationship between the petitioner and the beneficiary exists.
- Financial support — the affidavit of support (Form I-864) and its backing documents, which generally come into play at the green-card stage rather than at the moment the I-130 is filed.
The exact documents inside each category change with the relationship type and with the beneficiary's location. The four categories themselves do not.
Petitioner identity documents
The petitioner has to prove two things: their immigration status and their identity. USCIS lists the accepted forms of evidence on the Form I-130 instructions [Tier 1: USCIS.gov Form I-130 page, https://www.uscis.gov/i-130].
- For a US citizen petitioner — a copy of a birth certificate showing birth in the United States, a Certificate of Naturalization, a Certificate of Citizenship, an unexpired US passport, or a Consular Report of Birth Abroad.
- For a lawful permanent resident petitioner — a copy of the front and back of the Permanent Resident Card (Form I-551), or other evidence of permanent-resident status.
A frequent stumbling point is an expired status document or a copy that does not show both sides of a green card. USCIS treats an incomplete status showing as grounds for a Request for Evidence, which adds time to the case.
Beneficiary identity documents
Standard documents
The beneficiary's identity is usually shown with a small, predictable set of civil documents:
- A copy of the beneficiary's birth certificate.
- A copy of the beneficiary's passport biographic page, where one exists.
- Passport-style photographs when the instructions call for them.
- If the beneficiary has used other names, evidence of the legal name change (a marriage certificate or court order).
When foreign records are incomplete (substitution)
Some countries do not keep the civil records the United States takes for granted, or those records were destroyed or never issued. USCIS regulations anticipate this. Under 8 CFR §103.2(b)(2), when a required document is unavailable, the filer may submit secondary evidence in its place — and if secondary evidence is also unavailable, sworn affidavits [Tier 1: 8 CFR §103.2, https://www.law.cornell.edu/cfr/text/8/103.2].
The regulation sets an order of preference. A primary record (such as a government-issued birth certificate) is preferred. When that is genuinely unavailable, the filer typically includes a statement from the relevant civil authority confirming the record does not exist, then submits secondary evidence — for example baptismal records, school records, or census entries — that points to the same facts. Whether a particular substitution satisfies USCIS in a specific case is the kind of question a licensed immigration attorney can address.
Relationship evidence (per relationship type)
This is the heart of the I-130. The petition exists to establish a qualifying family relationship, and the documents that prove it differ sharply by relationship type [Tier 1: USCIS.gov Form I-130 page, https://www.uscis.gov/i-130].
Spouse cases
A spouse petition needs a copy of the marriage certificate, plus proof that any prior marriages on either side legally ended (divorce decrees, annulments, or death certificates). On top of the certificate, a spouse case carries a second burden the other categories do not: evidence that the marriage is bona fide — a real marriage rather than one entered to obtain an immigration benefit. That body of evidence is large enough to have its own walkthrough; see Proving a real marriage to USCIS.
Parent cases
When a US citizen petitions for a parent, the relationship is shown through the petitioner's own birth certificate naming the parent. The exact additional documents depend on the parent-child relationship — for example, a petition for a father may call for the parents' marriage certificate, and a petition relating to a step-parent or adoptive parent calls for the documents that created that relationship. The Form I-130 instructions list the variants [Tier 1: USCIS.gov Form I-130 page, https://www.uscis.gov/i-130].
Sibling and unmarried-child cases
A sibling petition (available only to a US citizen petitioner 21 or older) is proven by showing that the petitioner and the beneficiary share at least one common parent — usually with both siblings' birth certificates naming that parent. A petition for a child relies on the child's birth certificate naming the petitioner. These categories sit in the family-preference system rather than the immediate-relative system, which affects the wait after approval; the priority date and Visa Bulletin page explains that side of it.
Financial support documents
Family-based green-card cases require a sponsor to file an Affidavit of Support, Form I-864, a legally enforceable promise to support the immigrant financially [Tier 1: USCIS.gov Form I-864 page, https://www.uscis.gov/i-864]. The I-864 is generally not part of the I-130 package itself — it is filed later, either with an adjustment-of-status application or through the National Visa Center for consular processing. It belongs on the document map, though, because the income evidence behind it takes time to gather.
The supporting documents for the affidavit typically include the sponsor's federal tax returns or IRS tax transcripts, W-2 forms, and proof of current income such as recent pay statements or an employer letter. The mechanics — who can sponsor, the income thresholds, and when a joint sponsor is added — are covered on the affidavit of support page.
Translations and certifications
Any document in a foreign language has to be accompanied by a full English translation. The standard comes straight from the regulations: under 8 CFR §103.2(b)(3), the translator must certify that the translation is complete and accurate and that the translator is competent to translate from the foreign language into English [Tier 1: 8 CFR §103.2, https://www.law.cornell.edu/cfr/text/8/103.2].
- The translation has to cover the entire document, not just the parts that seem relevant.
- A signed translator's certification statement accompanies each translated document.
- The original-language copy is generally submitted alongside the translation, not in place of it.
Missing or partial translations are one of the most common reasons a family petition draws a Request for Evidence.
Common document mistakes
A handful of document errors show up again and again on family petitions:
- Submitting only one side of a green card when both the front and back are required.
- Foreign documents with no certified translation, or a translation that omits part of the original.
- Prior-marriage termination left unproven — a spouse case that does not include divorce or death documents for earlier marriages.
- Name mismatches across documents with no document connecting the two names.
- Skipping the unavailability statement before substituting secondary evidence, when 8 CFR §103.2(b)(2) expects an explanation of why the primary record is unavailable first.
Document requirements that hinge on unusual facts — a record that no longer exists, a complicated marital history, an adoption across borders — are the kind of question a licensed immigration attorney can address.
