Find a Superior Employment Immigration Lawyer for Every Stage of the U.S. Work Visa Journey

According to DocketWise, USCIS received 129,814 employment-based green card applications in fiscal year 2024, and behind every one of those cases is a foreign national or employer navigating a system that does not forgive procedural errors, missed deadlines, or the wrong visa category.

At Lightman Law Firm, our employment immigration attorneys work with individuals and companies at every stage of the process, from selecting the right visa classification to managing ongoing compliance after approval.

Employment-based immigration law draws from dozens of overlapping statutes, regulations, and USCIS policy updates. The Immigration and Nationality Act establishes the framework, but the practical reality of each case depends on current adjudication standards, processing backlogs, and the specific qualifications of each applicant.

Our team stays current on all of it so our clients do not have to.

Temporary Work Visa or Employment Green Card? A Side-by-Side Breakdown

Before selecting a visa category or filing a petition, it helps to understand the core distinction in U.S. employment-based immigration: whether you are pursuing temporary authorization to work in the United States or a path to permanent residency through an employment-based green card. These two routes follow different processes, timelines, and legal frameworks, and for many foreign nationals they are not mutually exclusive.

The table below outlines the key differences to help frame the decision:

Feature	Temporary Work Visa	Employment-Based Green Card
Best for	Foreign nationals who need work authorization in the U.S. for a defined period or while pursuing long-term options	Foreign nationals seeking lawful permanent residency and the ability to live and work in the U.S. indefinitely
Duration	Fixed term (typically 1-6 years, renewable)	Permanent (10-year card, renewable indefinitely)
Work Authorization	With a few exceptions, generally restricted to sponsoring employer and approved role	Must remain at sponsoring employer until approval (+6 months), after approval can work for any employer in virtually any occupation
Employer Sponsorship	Required in most cases	Required for most categories (EB-2 NIW and EB-1A are exceptions)
Labor Certification (PERM)	Not required	Required for EB-2 and EB-3; not required for EB-1, some EB-2 NIW
Path to Permanent Residency	Does not directly confer green card (but many visa holders pursue one)	Is permanent residency
Path to Citizenship	Not direct; must first obtain green card	Eligible to apply for naturalization after 5 years
Processing Time	Weeks to several months depending on visa type	At least one year (possibly multiple years) depending on category and country of birth
Annual Numerical Cap	Yes for some (H-1B subject to lottery; H-1B1 and E-3 are also capped but the limit is not typically reached so they are not subject to lottery)	Yes — 140,000 employment-based green cards issued annually
Family Members	Dependents may be eligible for derivative status (e.g., H-4, L-2)	Spouse and unmarried children under 21 included as derivatives
Geographic Flexibility	Generally tied to employer location and approved worksite	Tied to employer location and approved worksite until approval; after approval, can live and work anywhere in the United States
Self-Petition Option	Limited (O-1 with agent; E-2 for investors, and H-1B)	Available under EB-1A (extraordinary ability) and EB-2 NIW
Travel Outside the U.S.	Permitted with valid visa stamp and status	Permitted; re-entry on green card or travel document

How U.S. Employment Immigration Works, From Visa Category to Approval

U.S. employment-based immigration is not a single process. It has two distinct tracks, one for temporary work visas, one for employment-based green cards, that operate under separate legal frameworks, timelines, and filing requirements. Understanding how each unfolds from start to finish is essential for setting realistic expectations and avoiding costly mistakes.

How the Temporary Work Visa Process Unfolds: A Step-by-Step Look

Temporary work visas govern how foreign nationals enter the U.S. workforce on a nonimmigrant basis. The process varies by visa category, but the six steps below reflect the core sequence that most employment visa cases follow:

• Determine Your Immigration Goal: Temporary Work or Permanent Residency

  The first question is not which visa to file, it is what outcome you are working toward. Foreign nationals who need immediate work authorization while considering long-term residency options require a different strategy than those seeking a short-term assignment with no intention to remain permanently.

• Identify the Right Temporary Visa Category for Your Qualifications

  U.S. immigration law offers more than a dozen nonimmigrant work visa classifications, each with distinct eligibility requirements tied to your occupation, educational background, employer relationship, and country of citizenship. Filing under the wrong classification, even one that appears similar, can result in denial and lost time that cannot be recovered.

• Secure Employer Sponsorship or Establish Eligibility

  Most temporary work visas require a U.S. employer to act as the petitioner, demonstrate a legitimate job offer, and in some cases comply with Department of Labor prevailing wage requirements. A small number of visa categories, such as the O-1 filed through an agent, allow for arrangements that do not require a traditional employer-employee relationship.

• File the Nonimmigrant Petition With USCIS and Await Approval

  The employer files the appropriate petition, most commonly Form I-129, with U.S. Citizenship and Immigration Services, along with supporting documentation establishing eligibility. Premium processing is available for many visa categories and reduces the standard adjudication window to 15 business days for an additional government fee, or 45 days for NIWs and Multinational Executive positions.

• Complete Consular Processing or Change Status Inside the U.S.

  If the foreign national is abroad, a consular officer at a U.S. embassy or consulate reviews the approved petition and issues the visa stamp. If the foreign national is already in the United States in valid status, a change of status request filed alongside the USCIS petition may allow the transition to occur without leaving the country.

• Maintain Compliance and Track Your Visa Expiration Date

  A work visa approval is not permanent, status must be maintained through continuous authorized employment, and extensions must be filed before expiration. Gaps in status, even brief ones, can affect admissibility, eligibility for future benefits, and the green card process, making proactive deadline management a non-negotiable part of employment immigration compliance.

The 7-Step Path to an Employment-Based Green Card, Explained

Employment-based green cards offer permanent residency through one of five preference categories under the Immigration and Nationality Act. The process is significantly more involved than a temporary visa and, for applicants from certain countries, can span years due to per-country visa backlogs.

• Determine Whether You Qualify for an EB Preference Category

  The five employment-based preference categories, EB-1 through EB-5, have distinct eligibility standards based on qualifications, occupation, and in some cases investment capital. A thorough assessment of which category your background supports is the correct starting point, since filing under the wrong preference wastes time and resources without advancing your case.

• Identify Whether Employer Sponsorship or Self-Petition Applies to Your Case

  Most employment-based green card categories require a U.S. employer to sponsor the foreign national and file an immigrant petition on their behalf. EB-1A (extraordinary ability) and EB-2 National Interest Waiver allow qualified applicants to self-petition, meaning no employer sponsor is needed to initiate the process.

• Complete PERM Labor Certification if Required for Your Category

  EB-2 and EB-3 cases, except EB-2 NIW, require the employer to obtain a PERM labor certification from the Department of Labor before filing the immigrant petition. PERM requires the employer to document a full recruitment process demonstrating that no qualified, willing U.S. worker is available for the position. As of early 2026, the DOL’s PERM processing times average approximately 501 days, making early initiation of this step essential.

• File the Immigrant Petition (Form I-140) With USCIS

  Once PERM is approved or waived, the employer or self-petitioning applicant files Form I-140, Immigrant Petition for Alien Workers, with USCIS. This petition establishes eligibility for the green card category and locks in the applicant’s priority date, which determines their place in the visa queue.

• Wait for a Visa Number to Become Available Based on Your Priority Date

  The annual cap of 140,000 employment-based green cards, combined with per-country limits, creates backlogs for applicants from high-demand countries such as India and China. Applicants must monitor the monthly Visa Bulletin published by the U.S. Department of State to track when their priority date becomes current.

• Apply for Adjustment of Status or Complete Consular Processing Abroad

  Once a visa number is available, applicants inside the United States file Form I-485, Application to Register Permanent Residence or Adjust Status, with USCIS. Applicants outside the U.S. complete consular processing at a U.S. embassy or consulate, with both routes requiring medical examinations, biometrics, and background checks.

• Receive Your Green Card and Understand Your Ongoing Compliance Obligations

  Green card approval grants lawful permanent resident status, but new residents should understand the conditions that apply, including continuous residence requirements for naturalization eligibility and the circumstances under which status can be affected. EB-5 investors receive a conditional two-year green card and must separately file to remove conditions once their investment meets the job creation threshold.

7 Temporary Work Visas: Who Qualifies, What They Cover, & How Long They Last

Nonimmigrant work visas are not interchangeable, each classification targets a specific type of worker, employer relationship, or professional background, and choosing the right one determines what options are available to you later in the immigration process. The eight categories below represent the most commonly used employment visa paths for foreign nationals seeking to work in the United States:

• H-1B: Specialty Occupation Professionals

  The H-1B is available to foreign nationals working in specialty occupations that require at least a bachelor’s degree in a directly related field, covering roles such as engineers, software developers, physicians, and financial analysts. Due to the annual cap of 65,000 visas plus 20,000 for U.S. master’s degree holders, cap-subject petitions enter a lottery each spring.

• L-1: Intracompany Transferees and Multinational Executives

  The L-1 allows multinational companies to transfer employees who have worked abroad for the organization for at least one of the past three years to a U.S. office, subsidiary, affiliate, or parent. L-1A covers managers and executives with a maximum stay of seven years; L-1B covers employees with specialized knowledge with a maximum stay of five years.

• O-1: Individuals With Extraordinary Ability or Achievement

  The O-1 is reserved for individuals who have reached the top of their field through sustained national or international acclaim, with O-1A covering the sciences, education, business, and athletics, and O-1B covering the arts and motion picture and television industries. The visa is initially valid for up to three years and can be extended in one-year increments indefinitely.

• E-1 and E-2: Treaty Traders and Treaty Investors

  E-1 and E-2 visas are available only to nationals of countries that maintain qualifying commercial treaties with the United States, with the E-1 covering substantial trade between the U.S. and the treaty country, and the E-2 covering substantial investment in a U.S. commercial enterprise. Both categories extend to qualifying managers, executives, and essential skill workers who share the treaty nationality, and are renewable without a statutory maximum.

• TN: Professionals From Canada and Mexico

  The TN visa is available under the United States-Mexico-Canada Agreement for citizens of Canada and Mexico who will work in a specified list of professional occupations, including engineers, accountants, scientists, and lawyers. Canadian citizens apply directly at a U.S. port of entry without a USCIS petition; Mexican citizens must obtain a TN visa at a U.S. consulate abroad.

• R-1: Religious Workers

  The R-1 is available to foreign nationals who will serve as a minister or in another authorized religious occupation for a qualifying nonprofit religious organization with IRS tax-exempt status. Status is granted for an initial 30 months, extendable for another 30 months, for a maximum temporary stay of five years.

• E-3: Australian Nationals in Specialty Occupations

  The E-3 is available exclusively to Australian citizens in specialty occupations requiring a bachelor’s degree or higher in a related field, functioning similarly to the H-1B but under a separate statutory framework. The annual cap of 10,500 visas has never been fully utilized, meaning Australian nationals face no lottery risk and may apply at a U.S. consulate abroad.

EB-1 Through EB-5: Which Employment-Based Green Card Fits Your Profile?

Employment-based green cards are divided into five preference categories under the Immigration and Nationality Act, each designed for a distinct type of worker or investor. The right category depends on your credentials, your relationship with a U.S. employer, and in some cases your country of birth and its impact on visa availability.

The table below maps each classification to the applicant it is designed to serve:

Green Card Classification	Ideal Application
EB-1	Foreign nationals with extraordinary ability in the sciences, arts, education, business, or athletics who can document sustained national or international acclaim; outstanding professors or researchers sponsored by a U.S. institution; or multinational managers and executives transferring from a related foreign entity. No labor certification required.
EB-2	Professionals holding a U.S. master’s degree or foreign equivalent, or a bachelor’s degree plus five years of progressive work experience; workers with exceptional ability whose employment benefits the United States; or individuals pursuing a National Interest Waiver who can self-petition without employer sponsorship.
EB-3	Professionals with a U.S. bachelor’s degree or foreign equivalent in a qualifying field; skilled workers whose positions require at least two years of training or experience; or unskilled workers filling positions for which qualified U.S. workers are not available. Employer sponsorship and PERM labor certification are required.
EB-4	Special immigrants outside the standard employment framework, including certain religious workers, employees of U.S. foreign service posts, special immigrant juveniles, and other qualifying classifications defined by statute.
EB-5	Immigrant investors who invest a minimum of $1,050,000, or $800,000 in a targeted employment area, in a new U.S. commercial enterprise that creates or preserves at least 10 full-time jobs for qualifying U.S. workers.

9 Employment Immigration Mistakes That Get Strong Cases Denied… & How We Prevent Them

Employment-based immigration cases fail for reasons that have nothing to do with the applicant’s qualifications. Process errors, documentation gaps, and strategic missteps can derail cases that should have been approved without difficulty. The ten mistakes below represent the most common ways strong cases go wrong, and what Lightman Law Firm does to prevent each one:

1. Choosing the Wrong Visa Category From the Start

   Selecting a visa category that does not match the applicant’s qualifications or employment relationship creates problems that compound over time, often resulting in a denied petition, a subsequent refiling under the correct category, and lost time in the priority date queue. Our attorneys conduct a thorough eligibility review before any employment immigration petition is filed.

2. Missing Critical Filing Deadlines

   Work visa extensions, status changes, and green card filings all operate under strict deadlines, and an H-1B extension filed even one day after the status expiration date can result in a gap in authorized status. Our team tracks all filing windows proactively and builds in lead time so no deadline becomes a last-minute emergency.

3. Submitting Incomplete or Inconsistent Documentation

   USCIS adjudicators look for internal consistency across all submitted documents, job descriptions, degree transcripts, employment letters, and forms must all align precisely. A discrepancy between a job offer letter and the supporting labor condition application is a common trigger for Requests for Evidence, and every document package we prepare is reviewed for consistency before submission.

4. Failing to Maintain Continuous Legal Status Between Visa Changes

   Gaps in authorized status, even brief ones between a visa expiration and an extension approval, can accumulate unlawful presence, trigger inadmissibility bars, and complicate future applications. Our attorneys flag status continuity risks during employer changes, visa category transitions, and adjustment of status filings before they become problems.

5. Overlooking PERM Labor Certification Requirements

   PERM is the most procedurally demanding step in the EB-2 and EB-3 green card process, requiring a recruitment effort conducted in a specific sequence and documented in a precise format. A missed recruitment step, an improperly worded job advertisement, or a failure to properly consider U.S. worker applications can result in denial and force the employer to restart from the beginning.

6. Underestimating the Complexity of Requests for Evidence

   A Request for Evidence is not a denial, but it requires a precise, well-documented response within USCIS’s stated timeframe, typically 87 days, and an inadequate response frequently leads to denial. Our attorneys treat every RFE as a high-priority matter and build responses that directly address each identified deficiency with targeted evidence.

7. Neglecting to Track Priority Dates and Visa Bulletin Updates

   For applicants in the employment-based green card queue, the monthly Visa Bulletin determines when they can proceed to adjustment of status or consular processing, and missing a window when a priority date becomes current has real consequences. Our team monitors the Visa Bulletin on behalf of every client with a pending green card case.

8. Assuming Employer Sponsorship Guarantees Approval

   An employer’s willingness to sponsor a foreign national does not, on its own, satisfy USCIS requirements, the employer must also demonstrate financial ability to pay the offered wage, a genuine employer-employee relationship, and in PERM cases a properly documented recruitment effort. We work with both the employer and employee to ensure every element of the sponsorship meets USCIS standards.

9. Not Accounting for Processing Backlogs in Career or Life Planning

   A foreign national who files an EB-3 petition from India today is entering a priority date queue that extends years into the future, and planning a job change, career move, or family relocation without factoring in current processing times can lead to significant disruption. Our attorneys help clients understand the realistic timeline for their specific employment immigration case so that life decisions align with immigration strategy.

The 7 Most-Asked Questions About U.S. Employment Visas & Green Cards

Employment immigration law generates consistent questions from foreign nationals and employers encountering the process for the first time. The answers below address the questions our team hears most often that are not covered in detail elsewhere on this page:

• Can I Switch Employers While on an Employment-Based Visa?

  It depends on the visa type. H-1B holders can change employers through a portability provision that allows the worker to begin employment once USCIS receives the new petition, not after approval. L-1 holders are generally tied to the specific multinational organization that sponsored their petition and cannot transfer to an unrelated employer without changing visa status.

• What Happens to My Immigration Status If I Lose My Job?

  Involuntary job loss does not immediately terminate immigration status. H-1B, L-1, O-1, and most other employment-based nonimmigrant visa holders have a 60-day grace period from the date employment ends to find a new sponsoring employer, change to a different visa status, or depart the country. Contacting an immigration attorney as soon as a termination occurs is the most important first step.

• Can My Family Members Work If I Have an Employment Visa?

  Dependent family members in derivative status are authorized to live in the United States but are not automatically authorized to work. L-2 and E-3 spouses have automatic work authorization incident to their status, while H-4 spouses can apply for an Employment Authorization Document only if the primary H-1B holder has an approved I-140 petition.

• How Long Does an Employment-Based Green Card Application Take?

  The timeline varies by preference category, country of birth, and whether PERM labor certification is required. For applicants not subject to per-country backlogs, the full process from PERM filing through green card approval typically takes two to four years. For applicants from India and China in the EB-2 and EB-3 categories, wait times extend considerably longer due to per-country numerical limits.

• What Is a Priority Date and Why Does It Matter?

  A priority date marks an applicant’s place in the employment-based green card queue, it is either the date the employer files the PERM labor certification with the Department of Labor, or the date USCIS receives the I-140 petition for cases that skip PERM. An applicant cannot file for adjustment of status or complete consular processing until their priority date is current in the monthly Visa Bulletin.

• Can I Apply for a Green Card Without an Employer Sponsor?

  Yes, in three specific circumstances:

  • EB-1A allows individuals with extraordinary ability in the sciences, arts, education, business, or athletics to self-petition without a job offer.
  • EB-2 National Interest Waiver allows individuals with exceptional ability or an advanced degree to self-petition by demonstrating that their work substantially benefits the United States.
  • EB-5 is a self-petitioned route because eligibility is entirely rooted in the investor’s own personal capital infusion and its direct role in creating ten American jobs, meaning the investment itself serves as the sole “sponsor” of the green card.
• What Is the Difference Between an RFE and a Denial?

  A Request for Evidence is a notice from USCIS indicating that additional documentation or clarification is needed before the petition can be decided, it is not a denial, but it requires a complete response within the stated deadline, typically 87 days. A denial is a final adverse decision that can be appealed or reconsidered in some cases, though that process adds significant time and uncertainty to an already complex immigration process.
