Many people believe that the U.S. immigration process only begins when they apply for a Green Card or attend a consular interview. In reality, for most employment-based immigration categories, the case is largely determined starting with Form I-140.
This is not merely an administrative form; it is a legal petition demonstrating that you qualify to be classified under a specific employment-based immigrant category under U.S. immigration law. A well-prepared I-140 petition lays the foundation for the entire immigrant visa process that follows.
In this article, M-Consulting will help you understand what Form I-140 is, what factors USCIS evaluates, and more importantly, what you should prepare to improve your chances of approval on the first filing.
What Is Form I-140?
Form I-140 (Immigrant Petition for Alien Worker) is a petition used to classify an immigrant worker and is adjudicated by U.S. Citizenship and Immigration Services (USCIS).
The purpose of Form I-140 is for USCIS to confirm that a foreign worker meets all eligibility requirements for an employment-based immigrant category such as:
- EB-1A (Individuals of Extraordinary Ability)
- EB-1B (Outstanding Professors and Researchers)
- EB-1C (Multinational Managers or Executives)
- EB-2
- EB-2 National Interest Waiver (NIW)
- EB-3
Depending on the category, Form I-140 may be filed by:
- A U.S. employer;
- Or the applicant themself (for EB-1A and EB-2 NIW).
Why Is Form I-140 Considered the Key Stage of an Immigration Case?
Many people focus only on when a visa will be issued, but in practice, USCIS first determines whether you qualify as an employment-based immigrant.
If the I-140 is not approved:
- You cannot proceed with an immigrant visa application;
- You cannot adjust status using Form I-485;
- You cannot proceed with DS-260 consular processing;
- You will not have a Priority Date recorded for purposes of waiting for visa availability.
Simply put, I-140 is a core eligibility requirement, while the immigrant visa and Green Card are subsequent steps after USCIS has recognized that eligibility.
What Does USCIS Evaluate in an I-140 Petition?
This is where many applicants are often confused. USCIS does not look only at degrees or work experience; it also evaluates the overall logic and persuasiveness of the petition.
An I-140 petition is generally reviewed based on the following groups of criteria:
1. Legal Requirements of the Visa Category
Each visa category has different eligibility criteria. For example:
- EB-1A requires proof of extraordinary ability.
- EB-2 NIW requires demonstrating that the proposed endeavor provides substantial benefit to the United States.
- EB-3 requires meeting the requirements of the offered position and the PERM Labor Certification.
2. Applicant Qualifications
USCIS may evaluate:
- Educational background
- Professional experience
- Professional achievements
- Research work
- Awards
- Publications
- Leadership roles
- Level of influence in the field
Having a large volume of documents is not enough. What matters is that all evidence supports a consistent professional narrative.
3. Supporting Evidence
Always remember that quality matters more than quantity. A strong petition commonly includes:
- Employment Verification Letter
- Recommendation Letter
- Academic Transcript
- Degree Evaluation
- Professional license (if applicable)
- Employment contract
- Company documentation
- Evidence of achievements
Priority Date – Why Should You File Form I-140 as Early as Possible?
For many EB categories, especially EB-2 and EB-3, visa wait times depend on the Priority Date (your place in line for visa availability).
The Priority Date is established when:
- PERM is filed (if the category requires PERM), or
- USCIS receives Form I-140 (for categories that do not require PERM, such as EB-2 NIW).
This means:
If you qualify but delay filing, you may also delay the time when a visa becomes available later. That is why immigration professionals often recommend building and preparing the case early instead of waiting until everything feels “perfect.”
Common Mistakes That Can Lead to I-140 Denial
Through our consulting work, the M-Consulting team has found that many cases face difficulties not because applicants lack qualifications, but because they do not know how to present their qualifications according to USCIS standards.
Common mistakes include:
- Choosing the wrong immigration category from the beginning.
- Evidence that is not clearly tied to the legal criteria.
- Recommendation letters that are too generic and provide little evidentiary value.
- Listing achievements without explaining their significance.
- Inconsistent timelines across the petition.
- Insufficient documentation proving the applicant’s actual role.
- Failing to prepare a strategy for responding to a USCIS Request for Evidence (RFE).
How Does M-Consulting Support You?
Rather than simply helping complete forms, M-Consulting focuses on building a case strategy tailored to each client, including:
Monitoring case progress, assisting with RFE responses, and advising on next steps such as I-485 or DS-260.
Assessing eligibility for each EB category.
Analyzing strengths and areas that need improvement before filing.
Developing a case-building roadmap if the applicant is not yet eligible.
Guiding the preparation and organization of supporting evidence.
Preparing petition letters, recommendation letters, and professional documentation in line with USCIS standards.
Form I-140 is not merely a required form; it is the legal foundation of the entire U.S. employment-based immigration case. A sound strategy at this stage can help reduce risk, shorten processing time, and improve the likelihood of USCIS approval.
If you are considering EB-1, EB-2 NIW, or EB-3, start with a comprehensive case assessment. Understanding your own qualifications, choosing the appropriate visa category, and preparing suitable evidence can provide a significant advantage throughout your U.S. immigration journey.
