Employment-based immigration can play an important role in helping businesses hire, transfer, and retain foreign workers. For many employers, however, the process can be difficult to understand at the outset. A company may know that it wants to sponsor a worker, but not know whether the right option is an H-1B visa, an L-1 transfer, an O-1 petition, a religious worker visa, a temporary labor visa, or a permanent employment-based green card.
The correct path depends on the worker’s qualifications, the job duties, the employer’s business need, the expected length of employment, and the long-term immigration goal. Some employment visas are temporary and allow a foreign national to work in the United States for a specific employer, role, project, or period of time. Other employment-based options may lead to lawful permanent residence, commonly known as a green card.
Siri & Glimstad helps employers, organizations, professionals, and foreign workers evaluate employment-based immigration options and prepare the filings needed to move forward. Whether a company is hiring a specialty occupation worker, transferring an employee from an overseas affiliate, sponsoring an individual with extraordinary ability, or pursuing a permanent employment-based green card, experienced legal guidance can help avoid mistakes that delay or weaken a case.

Temporary Employment Visas
Temporary employment visas are generally used when a foreign national will work in the United States for a limited purpose, assignment, employer, or period of time. These visas do not automatically provide permanent residence, although some workers may later become eligible for a separate green card process.
For employers, the main challenge is often choosing the correct temporary visa category before preparing the petition. Each category has its own requirements. Some focus on the worker’s education. Others focus on the company’s temporary labor need, the relationship between foreign and U.S. business entities, the worker’s achievements, or the nature of the sponsoring organization.
H-1B Visas for Specialty Occupation Workers
The H-1B visa is one of the most familiar employment visa options for U.S. employers hiring foreign professionals. It is commonly used for positions that require highly specialized knowledge and at least a bachelor’s degree or equivalent experience in a specific field.
H-1B cases often involve workers in technology, engineering, healthcare, finance, education, business, research, and other professional fields. To qualify, the employer must show that the offered position is a specialty occupation and that the foreign worker has the required degree, credentials, or equivalent background for the role.
An H-1B petition usually requires careful attention to the job description, wage level, worksite, degree requirements, and the connection between the worker’s education and the position offered. Many H-1B cases are also affected by timing issues, including registration periods, cap limitations, lottery selection, start dates, extensions, transfers, and requests for evidence. For cap-subject H-1B cases, employers generally must first submit an electronic registration during the designated registration period. If there are more registrations than available H-1B numbers, USCIS conducts a selection process, often referred to as the H-1B lottery. Only selected registrations may proceed to the cap-subject petition stage, and selection in the lottery does not guarantee approval of the petition.
Employers should not treat H-1B sponsorship as a simple form filing. A weak job description, mismatched degree field, incorrect wage analysis, missed registration deadline, or incomplete employer documentation can create problems. An employment visa attorney can help evaluate whether H-1B is the right category, determine whether the case is subject to the cap or lottery process, and prepare the petition in a way that clearly explains the role, the worker’s qualifications, and the employer’s need.
H-2B Visas for Temporary Nonagricultural Workers
The H-2B visa allows certain U.S. employers to bring foreign workers to the United States for temporary nonagricultural jobs. This category is different from H-1B because it does not focus on specialty occupation professionals. Instead, it focuses on whether the employer has a qualifying temporary labor need.
H-2B cases may involve seasonal work, peak-load needs, intermittent needs, or a one-time occurrence. Employers in industries such as hospitality, landscaping, construction, seafood processing, recreation, and other labor-intensive fields may consider H-2B when they cannot find enough available U.S. workers for temporary positions.
These cases require planning. H-2B petitions involve both labor and immigration components, and employers must pay close attention to recruitment, timing, job terms, wage requirements, and filing windows. The category is also subject to numerical limitations, which can make timing especially important. When demand exceeds the available number of H-2B visas for a filing period, USCIS may use a random selection process for properly filed petitions received during the applicable filing window. For employers, this means that filing strategy, timing, and documentation must be handled carefully, but even a properly prepared filing may still be affected by the cap and selection process.
Because H-2B cases often involve multiple workers, strict deadlines, cap limits, and detailed employer obligations, mistakes can affect an entire hiring plan. Legal guidance can help employers determine whether the need is truly temporary, prepare the required documentation, understand how the cap and selection process may affect timing, and coordinate the process from labor certification through the immigration petition.
L-1 Visas for Intracompany Transfers
The L-1 visa is used when a company wants to transfer a qualifying employee from an office outside the United States to a related U.S. office. This category can be especially useful for international businesses that need to move executives, managers, or specialized knowledge employees into the United States.
There are two primary L-1 categories. L-1A applies to certain executives and managers. L-1B applies to employees with specialized knowledge. In either case, the employer must show a qualifying relationship between the foreign company and the U.S. company, such as a parent, branch, subsidiary, or affiliate relationship. The worker must also have qualifying prior employment with the foreign entity.
L-1 cases are often document-heavy. The petition may need to explain the corporate relationship, the worker’s role abroad, the proposed U.S. role, the business operations of each entity, and the need for the transfer. New office L-1 cases may require additional attention because the employer must show plans and resources for establishing or expanding U.S. operations.
For companies with international footprints, the L-1 visa can be a valuable option. It is also a category where details matter. Job titles alone are usually not enough. A strong petition should explain what the worker actually does, why the role qualifies, and how the transfer fits the company’s U.S. business needs.
O-1 Visas for Individuals With Extraordinary Ability or Achievement
The O-1 visa is available to certain individuals with extraordinary ability or achievement. Depending on the field, this category may apply to workers in the sciences, education, business, athletics, arts, motion picture, television, or other qualifying areas.
O-1 petitions are highly evidence-based. The issue is not simply whether the person is talented, successful, or respected. The petition must show that the individual meets the legal standard for the category. That often requires careful presentation of awards, publications, media coverage, judging work, original contributions, critical roles, high compensation, memberships, or other evidence relevant to the person’s field.
O-1 cases can be attractive because they may serve individuals whose accomplishments do not fit neatly into a traditional employer-sponsored visa category. Entrepreneurs, researchers, artists, executives, athletes, and professionals with unusual career paths may all consider O-1 eligibility, depending on the facts.
The strength of an O-1 petition often depends on how the evidence is selected, organized, and explained. An employment visa attorney can help identify the strongest evidence, address weaker areas, and present the case in a way that connects the person’s accomplishments to the applicable legal requirements.
R-1 Visas for Religious Workers
The R-1 visa is a temporary employment visa for certain religious workers. It may be available to ministers and other qualifying workers coming to the United States to work in a religious vocation or religious occupation for a qualifying religious organization.
R-1 cases are specialized. The petitioning organization must be eligible, and the position must qualify under the rules for religious work. The worker must also meet the membership and role requirements for the category. These cases may involve churches, temples, mosques, synagogues, religious schools, missionary organizations, and other religious entities.
Documentation is important in R-1 petitions. The sponsoring organization may need to provide evidence of its religious nature, tax status, structure, compensation arrangements, job duties, and ability to support the position. The worker’s religious background and proposed duties must also be explained clearly.
Because religious worker cases can receive close review, organizations should approach the process carefully. A petition that does not clearly explain the organization, the role, or the worker’s qualifications may face delays or additional scrutiny.

Permanent Employment-Based Immigration
Permanent employment-based immigration is different from temporary work authorization. Instead of allowing a foreign national to work in the United States for a limited period, a permanent employment-based case may lead to lawful permanent residence.
For many employers and foreign workers, the permanent process is part of a long-term retention strategy. A worker may first come to the United States in temporary status and later pursue an employment-based green card. In other situations, the permanent process may be the main immigration goal from the beginning.
The most common permanent employment-based categories include EB-1, EB-2, and EB-3. Many cases also involve additional steps, such as PERM labor certification, an I-140 immigrant petition, and either adjustment of status or consular processing.
EB-1 Green Cards for Priority Workers
The EB-1 category is for certain priority workers. It may apply to individuals with extraordinary ability, outstanding professors or researchers, and certain multinational executives or managers.
EB-1 can be an important option for highly accomplished individuals and qualifying multinational companies. Some EB-1 cases do not require PERM labor certification, which can make the category attractive when the facts support it. However, the standards can be demanding.
For individuals with extraordinary ability, the case must show sustained national or international acclaim. For outstanding professors or researchers, the evidence must show recognition in the academic field. For multinational executives or managers, the petition must establish the qualifying corporate relationship and the worker’s executive or managerial role.
EB-1 cases should be built with careful attention to evidence. A strong resume alone may not be enough. The petition should connect the worker’s background to the specific category requirements and present the case in a clear, persuasive way.
EB-2 Green Cards for Advanced Degree Professionals and Workers With Exceptional Ability
The EB-2 category may apply to advanced degree professionals and individuals with exceptional ability in the sciences, arts, or business. Many EB-2 cases are employer-sponsored and require PERM labor certification before the employer files the immigrant petition.
EB-2 may be appropriate when the position requires an advanced degree or when the worker has the level of expertise needed to qualify under the exceptional ability standard. In some cases, a National Interest Waiver may be available, allowing the applicant to request a waiver of the job offer and labor certification requirements.
For employer-sponsored EB-2 cases, the details of the job matter. The employer must define the role, requirements, and minimum qualifications carefully. The worker’s credentials must match the position, and the petition must show that the worker qualifies for the requested classification.
Because EB-2 cases can involve several stages, employers and workers should think ahead. Decisions made early in the process can affect later filings, timelines, and the strength of the overall green card case.
EB-3 Green Cards for Skilled Workers, Professionals, and Other Workers
The EB-3 category is another common employment-based green card option. It may apply to skilled workers, professionals, and certain other workers, depending on the job and the worker’s qualifications.
Many EB-3 cases require employer sponsorship and PERM labor certification. The employer must identify the job opportunity, complete the required labor process, and then file an immigrant petition showing that the worker qualifies for the offered position.
EB-3 can be useful for a wide range of employers and workers, but it still requires precision. The job requirements must be accurate, the recruitment process must be handled correctly, and the worker must meet the qualifications listed for the position. If the employer’s requirements are inconsistent, too restrictive, or poorly documented, the case may face problems later.
An employment-based immigration attorney can help employers evaluate whether EB-3 is appropriate, coordinate the PERM and I-140 stages, and avoid preventable errors that can slow down the green card process.
PERM Labor Certification
PERM labor certification is not a visa category, but it is a major step in many permanent employment-based green card cases. Through the PERM process, the employer generally tests the U.S. labor market and seeks certification from the Department of Labor before filing an immigrant petition with USCIS.
The PERM process requires careful planning. Employers must define the position, obtain a prevailing wage determination, conduct required recruitment, review applicants, and document the process. The employer must also be prepared to show that the job requirements are legitimate and that the process was conducted properly.
PERM mistakes can be costly. Problems with recruitment, job descriptions, wage levels, timelines, or documentation may delay the case or require the employer to restart the process. Since PERM often comes before the I-140 petition, errors at this stage can affect the entire permanent residence strategy.
Form I-140 Immigrant Petition
Form I-140 is the immigrant petition used in many employment-based green card cases. It is the step where the employer, or in some categories the applicant, asks USCIS to classify the worker under a specific employment-based immigrant category.
The I-140 petition must show that the worker qualifies for the category and that the offered position meets the applicable requirements. In employer-sponsored cases, the petition may also need to show the employer’s ability to pay the offered wage.
For EB-1, EB-2, and EB-3 cases, the I-140 stage is where eligibility is often tested closely. The petition should be consistent with the labor certification when PERM is required, and it should include the evidence needed to support the requested classification.
Adjustment of Status or Consular Processing
After the immigrant petition stage, the worker may still need to complete the final step toward lawful permanent residence. For workers already in the United States, this may involve adjustment of status. For workers outside the United States, this may involve consular processing through a U.S. embassy or consulate.
This stage can involve forms, medical exams, background checks, visa availability, family member filings, and review of the worker’s immigration history. Timing can depend on the employment-based category, country of chargeability, priority date, and government processing.
Employers and workers should not overlook the final stage. Even after an immigrant petition is approved, there may still be important issues to address before the worker becomes a lawful permanent resident.

Which Employment-Based Immigration Option Is Right for Your Situation?
There is no single employment-based immigration option that fits every employer or worker. A technology company hiring a software engineer may need a different strategy than a hotel seeking seasonal workers, a religious organization sponsoring a minister, a multinational company transferring an executive, or a researcher pursuing a permanent green card.
The right option depends on several factors, including the job duties, the worker’s education and experience, the employer’s business structure, the urgency of the need, the expected length of employment, and whether the goal is temporary work authorization or permanent residence.
Some cases also require thinking several steps ahead. A temporary visa may solve an immediate hiring need but may not be the best long-term option. A permanent green card process may support retention, but it can take time and may require detailed employer participation. In some situations, employers and workers may need to coordinate both temporary and permanent strategies.Â
