Common Documentation Errors That Lead to Delays or Denials

Missing documents, expired records, inconsistent information, and uncertified translations are among the most common filing mistakes. These issues often result in Requests for Evidence (RFEs) or longer processing times.

For employment-based cases, RFEs continue to affect thousands of applications annually, highlighting the importance of submitting complete evidence from the start.

Benefits of Preparing a Complete Immigration File

A well-organized immigration file makes it easier to respond to agency requests, prepare for interviews, and track important records throughout the process.

With USCIS handling millions of cases and ongoing backlogs, having complete documentation can help reduce avoidable delays and strengthen your application.

Core Documents Required for Nearly Every Immigration Application

Regardless of the immigration benefit being sought, most applicants are required to provide a set of basic identity and background documents. These records help immigration authorities verify who you are, your nationality, and your immigration history.

Valid Passport and Travel Documents

A valid passport is one of the most important immigration documents. Applicants should provide copies of the biographical page, current visas, entry stamps, and any other travel documents that support their immigration history.

Birth Certificate

Birth certificates are commonly required to verify an applicant's identity, age, place of birth, and family relationships. If the document is not in English, a certified translation is typically required.

Government-Issued Photo Identification

Applicants should include a government-issued photo ID, such as a national identity card, driver's license, or state-issued identification document, when available.

Passport-Style Photographs

Most immigration applications require recent passport-style photographs that meet government specifications. Incorrect photo sizes or outdated photos can result in processing delays.

Previous Immigration Records and Notices

Copies of prior visas, I-94 records, approval notices, employment authorization cards, green cards, and immigration correspondence can help establish an applicant's immigration history and current status.

Documents Proving Your Current Immigration Status

Before approving an application, immigration officials must confirm your current status in the United States. These records show how you entered the country, whether you are authorized to remain, and any immigration benefits previously granted.

Visa Records and Approval Notices

Your visa history helps establish your legal entry and immigration background. Include copies of all relevant visas and approval notices received from immigration authorities.

Key documents may include:

• Current and expired visa stamps

• Form I-797 Approval Notices

• Change or extension of status approvals

• USCIS receipt notices for pending cases

Form I-94 Arrival and Departure Records

The Form I-94 is one of the most important immigration documents because it shows when you entered the United States and how long you are authorized to stay.

Make sure to include:

• Most recent I-94 record

• Travel history records, if available

• Copies of previous I-94s for status changes or extensions

Why it matters: An incorrect or expired I-94 can create issues when applying for immigration benefits.

Green Card or Permanent Resident Documentation

If you are a lawful permanent resident, provide evidence of your permanent resident status. These documents help verify eligibility for renewals, family petitions, and naturalization applications.

Common examples include:

• Permanent Resident Card (Green Card)

• Conditional Green Card documents

• Green Card renewal notices

• Previous permanent resident records

Employment Authorization Documents (EAD)

An Employment Authorization Document proves that you are legally permitted to work in the United States while maintaining an eligible immigration status.

Include copies of:

• Current EAD card

• Previous EAD cards

• EAD renewal approvals

• Employment authorization notices from USCIS

Financial Documents Immigration Officials Commonly Request

Financial records help immigration authorities determine whether an applicant or sponsor can meet financial obligations and support themselves without relying on public assistance. Providing complete and up-to-date financial evidence can strengthen an application and prevent unnecessary delays.

Federal Tax Returns and Tax Transcripts

Tax records are among the most commonly requested financial documents, especially in family-based immigration cases involving sponsors.

Include:

• Federal tax returns from recent years

• Business licenses

• Invoices and client contracts

• Corporate formation documents

Family-Based Immigration Document Checklist

Family-sponsored immigration cases rely heavily on documents that prove a qualifying relationship between the petitioner and beneficiary. According to USCIS data, family-sponsored categories continue to account for a significant share of green card approvals each year, making relationship evidence one of the most closely reviewed parts of an application.

Marriage Certificates

A valid marriage certificate is required when applying for immigration benefits through a spouse. The document should clearly show the names of both spouses and the official date and place of marriage.

Include:

• Certified marriage certificate

• Certified English translation (if applicable)

• Records of any prior marriages

Birth Certificates for Family Relationships

Birth certificates help establish parent-child and sibling relationships for immigration petitions.

Common uses include:

Divorce Decrees and Death Certificates

Supporting documents may include:

• Final divorce decrees

• Annulment records

Proof of a Bona Fide Marriage

For marriage-based immigration cases, applicants must show that the relationship is genuine and not entered into solely for immigration benefits.

Strong evidence can include:

• Insurance policies listing both spouses

• Affidavits from friends and relatives

Checklist Reminder: The strongest family-based cases combine official civil records with evidence showing an active, ongoing family relationship over time.

According to USCIS data, employment-based immigrants receive hundreds of thousands of green cards annually, making accurate employment documentation essential for approval.

Employment Offer Letters

A formal job offer helps establish the position being offered and the employer's intent to hire the applicant.

Include:

• Signed employment offer letter

• Job title and duties

• Salary information

• Pay records and tax documents

• Resumes and professional portfolios

Checklist Reminder: Strong employment-based cases combine employer documentation, educational credentials, and verifiable work experience to clearly demonstrate eligibility for the requested immigration benefit.

Medical and Background Documents Required for Immigration

Medical and background checks are an important part of many immigration applications. These documents help immigration authorities determine whether an applicant meets health-related and admissibility requirements before a visa, green card, or other benefit can be approved.

Immigration Medical Examination Forms

Many applicants must complete an immigration medical exam performed by an authorized physician and submit the required medical documentation.

Typically includes:

• Completed immigration medical examination form

• Additional vaccine documentation required by immigration authorities

These documents help verify:

• Criminal history, if any

• Residence history in specific countries

• Compliance with immigration screening requirements

Important: Requirements vary depending on age, immigration category, and country of residence.

Applicants with prior arrests, charges, or convictions should be prepared to provide complete court documentation, even if charges were later dismissed.

Examples include:

• Court dispositions

• Arrest records

• Sentencing documents

• Expungement or dismissal records

Checklist Reminder: Always submit complete and accurate background information. Failing to disclose required records can create more serious immigration issues than the incident itself.

Proof of Residence and Address History

Quick Tip: The more organized and consistent your supporting evidence is, the easier it becomes for immigration officers to verify your case.
