What is a U.S. work visa?
A work visa allows certain foreign nationals to enter the United States to engage in authorized employment activities, provided they meet the requirements of the corresponding category. Some visas are temporary, while other employment-based immigration categories can lead to permanent residence, also known as a Green Card.
Many employment visas require a job offer and sponsorship from a U.S. employer. Depending on the category, a petition with U.S. Citizenship and Immigration Services (USCIS), a labor certification from the Department of Labor (DOL), or other specific requirements may also be necessary.
Selecting the correct category is essential to determine what documents you need, who must file the application, and the steps you must follow.

Types of available work visas
The United States has different visa categories for foreign workers. Among the best-known options are the H-1B, L-1, O-1, and TN visas. Each has unique requirements, eligibility conditions, and specific limitations.
Some allow temporary work for a specific employer, while others are designed for intracompany transfers or individuals with extraordinary abilities. Below, we explain their main characteristics.
H-1B Visa: Professionals in specialty occupations
The H-1B visa is a nonimmigrant category intended for certain workers who will fill specialty occupations requiring the theoretical and practical application of specialized knowledge and, generally, a specific bachelor’s degree or its equivalent.
Professional fields that may include eligible positions include:
- Engineering.
- Information Technology and Computing.
- Finance and Accounting.
- Medicine and certain health-related occupations.
Eligibility depends on the job duties, professional requirements, and qualifications of the applicant. The employer generally must file a petition with USCIS and comply with applicable labor requirements. Some applications are also subject to numerical limits and selection procedures.
When the profession requires a state or local license, additional requirements may apply to legally practice the occupation.
L-1 Visa: Intracompany transfers
The L-1 visa allows certain companies to transfer employees from a foreign office to a related office in the United States. It is an option for multinational organizations that need to relocate qualified personnel to perform executive, managerial, or specialized knowledge functions.
This category is divided into two main modalities:
- L-1A: For executives and managers who meet the category’s requirements.
- L-1B: For employees who possess specialized knowledge of the organization’s products, services, processes, or procedures.
Generally, the worker must have been employed abroad by a qualified organization for at least one continuous year within the applicable three-year period prior to their admission to the United States or the corresponding application, depending on the circumstances of the case.
The U.S. employer files the petition with USCIS and must demonstrate that the requirements of the business relationship and the position are met. Options may also exist for companies looking to establish a new office in the United States.
O-1 Visa: Individuals with extraordinary ability
The O-1 visa is directed at individuals who have demonstrated extraordinary ability in certain professional or artistic fields, or extraordinary achievement in the motion picture or television industry, according to the corresponding modality.
The main categories are:
- O-1A: Individuals with extraordinary ability in sciences, education, business, or athletics.
- O-1B: Individuals with extraordinary ability in the arts or extraordinary achievement in the motion picture or television industry.
- O-2: Certain workers accompanying O-1 artists or athletes to assist in specific events or performances.
- O-3: Spouses and children who qualify to accompany certain O-1 or O-2 visa holders.
The application requires documentary evidence to evaluate achievements, professional recognition, and compliance with the category’s criteria. An outstanding career track record can be relevant, but each case must be analyzed individually.
TN Visa: Professionals from Mexico and Canada
The TN visa, established under the United States-Mexico-Canada Agreement (USMCA), allows certain Mexican and Canadian citizens to apply for temporary admission to the United States to engage in professions covered by the agreement.
Professions that may qualify, depending on specific requirements, include:
- Accountants.
- Architects.
- Engineers.
- Registered Nurses.
To be eligible, you generally must meet the following conditions:
- Be a citizen of Mexico or Canada. Permanent residence in these countries does not substitute for the citizenship requirement.
- Qualify to practice a profession included in the TN category.
- Have a job offer or professional agreement that meets applicable requirements.
- Possess the degrees, licenses, or credentials required for the profession.
- Request temporary admission to perform authorized professional activities.
The TN classification is not available to all nationalities or for any occupation. Therefore, it is important to verify the requirements before starting the process.

Requirements to apply for a U.S. work visa
Requirements vary depending on the immigration category, profession, and circumstances of the applicant. Depending on the type of visa, the process may require:
- A job offer or professional agreement that complies with the category’s requirements.
- A petition filed by the employer or sponsor when applicable, such as Form I-129 for certain nonimmigrant visas.
- Academic documentation and evidence of professional experience.
- Proof of extraordinary ability or professional recognition, when applicable to the O-1 category.
- A valid passport and documentation required for consular processing.
- Payment of applicable fees, according to employer and applicant responsibilities.
It is important to distinguish between temporary work visas and categories that allow application for employment-based permanent residence. A temporary visa does not automatically grant a Green Card, although certain immigration pathways may allow a person to apply for residency if they meet the corresponding requirements.
Before submitting an application, it is wise to verify which documents are necessary and whether the employer must complete additional procedures with USCIS or the Department of Labor.
What is the process to obtain a work visa?
Although the procedure depends on the chosen category, obtaining a work visa usually involves several stages:
- Profile evaluation: Identify the immigration category that may correspond to your profession, experience, and goals.
- Job offer and sponsorship: Secure a job offer or establish the professional relationship required by the category.
- Petition preparation: The employer or sponsor files the corresponding application with USCIS when required.
- Application review: USCIS evaluates the petition and may request additional evidence.
- Consular processing or admission: Depending on the category and the applicant’s situation, completing consular processing or requesting admission at a port of entry may be necessary.
- Start of authorized employment: Once the corresponding immigration requirements are met, the worker may perform the authorized activities.
Specific documentation may include university degrees, certifications, letters from previous employers, a professional resume, and evidence of experience or achievements. Not all of these documents are mandatory for every category, so they must be prepared according to the specific case requirements.
If you wish to travel with your family, it is also important to verify whether your category allows your spouse and children to apply for dependent status and what conditions apply.
Frequently asked questions about U.S. work visas
What is the difference between the H-1B and L-1 visas?
The H-1B visa is intended for certain workers filling specialty occupations. The L-1 visa allows the transfer of qualified employees from a related foreign company to an office in the United States, provided the requirements of the category are met.
How long does a work visa last?
Duration depends on the category and approval conditions. For example, the H-1B classification generally allows an initial period of up to three years and typically an extension of up to six years in total, with exceptions applicable under certain circumstances. The L-1A classification has a general maximum limit of seven years, while the L-1B has a general maximum limit of five years. Rules may vary based on the case and time previously used in certain classifications.
Who pays the application fees?
Responsibility for costs depends on the immigration category and the type of expense. Some fees and obligations must be assumed by the employer, while other consular or personal expenses may correspond to the applicant. Specific rules should be reviewed before filing the petition.
Can I bring my family with a work visa?
Some categories allow eligible spouses and children to apply for dependent status. For example, H-4, L-2, and O-3 classifications exist. Work authorization rights and stay conditions vary depending on the category and the status of each family member.
Does a work visa allow me to obtain permanent residence?
Not automatically. Temporary work visas and permanent residency are distinct categories. Some individuals may qualify to apply for a Green Card through an employment-based immigration pathway, but they must meet the corresponding criteria and complete the applicable procedure.
