Evidentiary and Signature Standards in U.S. Immigration Filings

Accurate documentation, reliable supporting evidence, and properly executed signatures are essential to the successful preparation and adjudication of U.S. immigration petitions and applications. The Department of Homeland Security (DHS), U.S. Citizenship and Immigration Services (USCIS), and the U.S. Department of Labor (DOL) impose specific evidentiary, documentary, and signature requirements depending on the immigration benefit or employment-based filing.

Failure to satisfy these requirements may result in a Request for Evidence (RFE), Notice of Intent to Deny (NOID), rejection, or denial. In certain circumstances, deficiencies involving signatures may also affect the filing date and result in the loss of filing fees.

Recent DHS and USCIS developments in 2026 make it particularly important for applicants, petitioners, and employers to verify the authenticity, completeness, consistency, and legal sufficiency of all submitted documentation.

1. Evidentiary Standards Under USCIS Regulations

Under 8 C.F.R. § 103.2(b), applicants and petitioners bear the responsibility of establishing eligibility for the requested immigration benefit through credible, relevant, and sufficient documentation.

USCIS generally evaluates evidence under the applicable legal standard, commonly the preponderance of the evidence standard, where applicable. This requires demonstrating that a claimed fact is more likely than not to be true. The evidence must establish eligibility under the relevant statutory and regulatory requirements rather than merely support an applicant’s general qualifications.

USCIS distinguishes between the following categories of evidence:

• Primary evidence: Original or authoritative records, such as educational certificates, employment records, tax documents, birth certificates, and official government records.
• Secondary evidence: Alternative documentation submitted when primary evidence does not exist or cannot reasonably be obtained.
• Affidavits and declarations: Statements from individuals with personal knowledge of the relevant facts, particularly when primary and secondary documentation is unavailable.

Generally, primary evidence should be submitted when available. If it is unavailable, the petitioner should explain its unavailability and provide appropriate secondary evidence. Affidavits may be used when both primary and secondary evidence are unavailable, subject to applicable USCIS requirements.

2. Document Authenticity, Consistency and Translation Requirements

Supporting documentation must be authentic, legible, complete, and consistent with the information provided in the relevant immigration petition or application.

Under 8 C.F.R. § 103.2(b)(3), documents containing foreign-language text must be accompanied by a complete English translation. The translator must certify that the translation is complete and accurate and that the translator is competent to translate the foreign language into English.

Furthermore, under 8 C.F.R. § 103.2(b)(4), applicants generally may submit legible photocopies of supporting documents unless an original is specifically required by the applicable regulations, form instructions, or USCIS request.

Particular attention should be given to discrepancies involving:

• Employment dates, job titles, duties, and salary information.
• Educational qualifications, transcripts, and degree certificates.
• Employer information, work locations, and organizational details.
• Tax returns, payroll records, and financial documentation.
• Previous immigration filings and statements made to government agencies.

Inconsistencies between the petition, supporting evidence, and previous immigration records may raise questions about the reliability of the submission and require additional explanation.

3. USCIS Signature Requirements and the 2026 Regulatory Update

Important regulatory update – July 10, 2026

DHS issued an interim final rule titled Signatures on Immigration Benefit Requests, published on May 11, 2026, and effective July 10, 2026. The rule amended 8 C.F.R. § 103.2(a)(7)(ii)(A) to expressly authorize USCIS to reject or deny a benefit request if it subsequently determines that the request was not submitted with a valid signature.

Under 8 C.F.R. § 103.2(a)(2), an applicant or petitioner generally must personally sign the benefit request. By signing, the individual certifies under penalty of perjury that the information in the application or petition and its supporting evidence is true and correct.

The principal signature requirements include:

1. Handwritten signatures: A valid handwritten signature must reflect the signer’s knowledge and approval of the contents of the filing. A signature may be abbreviated or illegible, provided it represents the signer’s genuine signature.
2. Scanned or reproduced signatures: USCIS generally accepts photocopied, scanned, or faxed copies of documents containing an originally handwritten signature, unless otherwise specified. However, inserting a previously saved signature image, copy-pasting a signature, or using a stamped or typewritten name in place of an actual signature does not satisfy the ordinary handwritten-signature requirement.
3. Electronic signatures: Electronic signatures are acceptable for benefit requests filed electronically when specifically permitted by the applicable USCIS form instructions and procedures.
4. Authorized signatories: Parents or legal guardians may sign in the limited circumstances permitted by regulation. Attorneys, preparers, and representatives generally cannot sign a benefit request on behalf of the applicant or petitioner merely because they are handling the filing.

Importantly, the July 2026 rule provides that even if USCIS initially accepts a filing, it may subsequently reject or deny the request if a deficient signature is discovered. Therefore, signature verification must take place before submission, not merely during the initial filing process.

4. Department of Labor (DOL) Evidentiary and Signature Requirements

Employment-based immigration matters involving PERM labor certification and Labor Condition Applications (LCAs) are also subject to specific Department of Labor requirements.

A. PERM Labor Certification – ETA Form 9089

Under 20 C.F.R. § 656.17(a), employers must submit a properly completed ETA Form 9089. Incomplete applications may be denied.

The regulation addresses the execution of electronically certified applications and applications submitted by mail. Electronically filed and certified applications must be signed immediately upon receipt of the labor certification, while mailed applications must contain the required original signatures when received by the processing center.

Employers must also maintain supporting recruitment documentation and provide it when selected for an audit or requested by the Certifying Officer.

B. Labor Condition Applications – H-1B, H-1B1 and E-3

Under 20 C.F.R. § 655.730, employers or their authorized representatives must submit accurate LCAs using ETA Form 9035 or 9035E.

By signing the LCA, the employer attests to the accuracy of the information and accepts the applicable obligations concerning wages, working conditions, and other labor-condition requirements.

For electronically filed LCAs, the employer or authorized representative must print and sign the certified LCA immediately after certification. The employer must retain the required signed documentation and make it available for public examination under 20 C.F.R. § 655.760.

These requirements are particularly important because inaccurate wage information, employment locations, or employer attestations may create compliance issues beyond the USCIS petition itself.

5. Consequences of Noncompliance

Failure to comply with evidentiary and signature requirements can have significant immigration consequences, including:

• Rejection of an improperly executed application or petition.
• Denial where USCIS determines that required evidence is insufficient or a signature is invalid.
• Issuance of an RFE or NOID, where appropriate under applicable procedures.
• Delays in adjudication and additional legal expenses.
• Potential findings involving credibility, material inconsistencies, or misrepresentation where supported by the facts.

Importantly, USCIS is not required to issue an RFE in every case involving insufficient evidence. Under 8 C.F.R. § 103.2(b)(8), USCIS may deny a request where the record does not establish eligibility and the applicable circumstances do not warrant an RFE or NOID. Applicants should therefore avoid relying on an opportunity to correct deficiencies after filing.

1. Verify all signatures before filing: Ensure that the appropriate individual has personally reviewed and properly signed every document requiring a signature.
2. Maintain supporting records: Preserve original educational, employment, payroll, tax, recruitment, and corporate records.
3. Ensure documentary consistency: Cross-check information across immigration forms, previous filings, employer records, and supporting documents.
4. Provide certified translations: Submit complete English translations with the required translator certification for all foreign-language documents.
5. Maintain DOL compliance records: Employers should preserve PERM recruitment documentation, signed LCAs, and public access file materials as applicable.
6. Obtain legal review before submission: Have an experienced immigration legal professional review the filing to identify potential evidentiary gaps, inconsistencies, and signature deficiencies.

Conclusion

Evidentiary sufficiency and proper signature execution are fundamental requirements in U.S. immigration proceedings. The 2026 DHS regulatory update reinforces the importance of submitting properly signed benefit requests and makes clear that acceptance at initial filing does not necessarily protect a petition from subsequent action based on an invalid signature.

Applicants and employers should adopt a proactive compliance approach by maintaining reliable documentation, verifying signatures, and ensuring that all submissions satisfy the applicable USCIS and DOL requirements. Proper preparation and legal review can help minimize avoidable filing errors and strengthen the overall presentation of an immigration case.
