Navigating the U.S. immigration system to secure a work visa requires meticulous documentation of your education, work experience, and skills. Whether you’re applying for an H-1B specialty occupation visa, an L-1 intra-company transfer visa, or an employment-based green card, proving your qualifications is a critical step. The U.S. Citizenship and Immigration Services (USCIS) and the Department of Labor (DOL) set strict standards to ensure that foreign workers meet the eligibility criteria for their intended positions.
Why Proving Work Experience and Qualifications Matters
In FY 2024, USCIS received over 470,000 H-1B petitions, but due to the statutory cap, only 85,000 visas were available annually – 65,000 under the regular cap and 20,000 for advanced degree holders. This competitive landscape underscores the need for accurate documentation. For employment-based immigration, such as the EB-2 or EB-3 categories (which issue approximately 140,000 visas annually), the stakes are equally high. Employers and petitioners must demonstrate that the petitioner’s qualifications match the job requirements and that there are no qualified U.S. workers available to fill the position – a process that is often validated through labor certification or credential evaluations.
Failure to provide adequate evidence can result in a Request for Evidence (RFE) or outright denial. In 2023, USCIS issued RFEs on 17% of H-1B petitions, with many related to insufficient evidence of qualifications or specialty occupation status. To avoid such setbacks, follow these actionable steps.
Step-by-Step Guide to Proving Your Qualifications
Step 1: Evaluate Visa Requirements
Each U.S. work visa has specific eligibility criteria. For example:
- H-1B visa: Requires a bachelor’s degree or equivalent in a field related to the specialty occupation, plus evidence of specialized knowledge.
- L-1 Visa: Requires at least one year of employment with a qualifying foreign entity within the last three years, with evidence of managerial or specialized duties.
- EB-2/EB-3 Green Cards: Often require a degree plus five years of progressive experience (EB-2) or two years of skilled work (EB-3), along with a DOL labor certification.
Start by checking the USCIS website (uscis.gov) for the specific requirements of your visa category. A mismatch between your credentials and the job description may result in denial.
Step 2: Gather Educational Documentation
Your transcript is the foundation of your application. Here’s how to prepare them:
- Obtain official transcripts and diplomas: Request certified copies from your educational institution. If your degree is from outside the U.S., USCIS typically requires a credential evaluation to confirm its U.S. equivalency.
- Credential Evaluation: Use a recognized evaluator such as World Education Services (WES) or a member of the National Association of Credential Evaluation Services (NACES). In 2024, WES processed over 200,000 evaluations for U.S. immigration purposes, with costs ranging from $100 to $250 depending on the type of report (document-by-document or course-by-course).
- Translations: If documents are not in English, hire a certified translator. USCIS denied 3% of petitions in 2023 due to missing or uncertified translations.
For healthcare professionals seeking employment-based visas (e.g., nurses under Schedule A), the CGFNS VisaScreen® service is mandatory to verify education, licensure, and English proficiency.
Step 3: Document your work experience
Proving work experience is often the most difficult step, especially if your education alone doesn’t meet visa requirements. Here’s how to do it:
- Employer Reference Letters: Obtain detailed letters on company letterhead from current and former employers. These should include
- Job title and dates of employment (e.g., “Software Engineer, June 2019-March 2025”).
- Specific duties and skills relevant to the visa job (e.g., “Developed Java-based applications using agile methodologies”).
- Hours worked per week (full-time is typically 35-40 hours).
- Signatory’s name, title, and contact information.
- Progressive Experience: For H-1B or EB-2 visas, demonstrate increasing responsibility. For example, a letter might state, “Promoted from Junior Developer to Team Lead, managing five engineers.
- USCIS “Three-for-One” Rule: In the absence of a degree, three years of relevant work experience can substitute for one year of college education. In 2024, Carnegie Evaluations reported a 15% increase in H-1B petitions successfully using this rule.
If an employer is unavailable (e.g., company closure), affidavits from co-workers or supervisors, notarized and paired with pay stubs or tax records, may suffice.
Step 4: Obtain professional certifications (if applicable)
Certifications can strengthen your case, especially for technical roles. For example:
- An IT professional might include a Cisco CCNA or AWS certification.
- A nurse might submit NCLEX-RN results along with state licensure.
In 2025, DOL data show that 68% of H-1B petitions in STEM fields included supplemental certifications, increasing approval rates by 10% over those without.
Step 5: Combine education and experience (if necessary)
For visas such as H-1B, where a bachelor’s degree is required but not possessed, a work experience assessment can fill the gap. Agencies such as International Evaluations evaluate your experience against USCIS standards, often requiring
- A detailed resume.
- Letters from employers confirming roles and responsibilities.
- Academic transcripts (if available).
In 2024, these evaluations helped more than 12,000 applicants achieve degree equivalency, with a typical processing time of 7-14 days and a cost of $300-$500.
Step 6: Review and Submit Documentation
- Cross-check the job description: Make sure your documentation matches the job posting and labor certification (if applicable). Mismatches triggered 22% of RFEs in 2023.
- E-Verify Enrollment: Some employers must confirm your eligibility through E-Verify (e-verify.gov), used by over 1 million companies in 2024.
- File Promptly: Submit your petition with Form I-129 (for H-1B/L-1) or I-140 (for EB categories), including all supporting documents.
Step 7: Respond to RFEs (if received)
If USCIS requests additional evidence, respond within the 90-day window (standard as of 2025). Common RFE triggers include vague job duties or unverified experience. Consult an immigration attorney to strengthen your response.
Key Data and Insights (April 2025)

Tips for success
- Start early: Evaluations of credentials and letters of recommendation can take weeks. In 2024, delays in document preparation caused 8% of H-1B petitioners to miss the filing window.
- Be specific: Vague job descriptions (e.g., “worked on projects”) weaken your case. Use technical details (e.g., “optimized SQL databases for 20% faster queries”).
- Consult experts: Immigration attorneys or evaluation services can identify gaps before submission.
Conclusion.
Proving work experience and qualifications for a U.S. work visa requires precision, from securing evaluated transcripts to drafting detailed employer letters. After April 2025, the process remains competitive, but manageable with proper preparation. By following these steps-evaluating requirements, documenting credentials, and aligning evidence with USCIS standards-you can increase your chances of approval. The investment in time and resources (typically $500-$1,000 total for evaluations and translations) paves the way for career opportunities in the U.S., where skilled workers remain in high demand.
