Introduction

Relocating to the United States for work involves navigating one of the world’s most complex immigration systems. Unlike many countries that use a single skilled worker visa category, the US offers multiple employer-sponsored visa types, each designed for specific employment situations, qualifications, and organisational structures.

For international employees transferring to a US office or joining an American employer, understanding which visa category applies to your situation is the first step in a successful relocation. The most common employer-sponsored work visas include H-1B for specialty occupation workers, L-1 for intracompany transferees, and O-1 for individuals with extraordinary ability, among others.

This guide provides an overview of the primary US work visa categories available for skilled professionals, the application process, compliance obligations, and practical considerations for relocating employees and their families. While your employer and immigration counsel will determine the appropriate visa category and handle the legal aspects of your petition, this resource helps you understand what to expect throughout the process.

Important: Immigration decisions require qualified legal counsel. This guide provides educational context only and does not constitute legal advice. MovePlus supports organisations by centralising documentation, tracking compliance timelines, and coordinating the relocation process through the MOVEPLUS™ platform, but does not provide immigration legal services.

Understanding US work visa categories for corporate employees

The United States immigration system distinguishes between temporary work visas and permanent residence pathways. Most corporate relocations begin with a temporary work visa that authorises employment for a defined period, with the option to pursue permanent residency later if desired.

Temporary work visas vs permanent residence

Temporary work visas permit foreign nationals to work in the US for a specific employer and role for a limited duration. These visas are tied to the sponsoring employer and typically require renewal or extension to maintain status beyond the initial validity period.

Permanent residence (a green card) provides indefinite work authorisation and is not tied to a specific employer. While some temporary work visas allow dual intent (the ability to simultaneously hold temporary status and pursue permanent residence), others do not. This guide focuses on temporary employer-sponsored work visas, as these represent the entry point for most corporate assignments.

Common employer-sponsored visa categories

Your employer and immigration lawyer will determine which visa category applies to your situation based on your role, qualifications, and the company organisational structure. The most common categories for skilled professionals include:

• H-1B: Specialty occupation workers in fields requiring at least a bachelor’s degree or equivalent
• L-1: Intracompany transferees moving from a foreign office to a US office of the same employer
• O-1: Individuals with extraordinary ability or achievement in their field
• E-2 and E-3: Treaty investor employees (E-2) and Australian specialty occupation workers (E-3)
• TN: Canadian and Mexican professionals under the USMCA (formerly NAFTA)

Each category has distinct eligibility requirements, application procedures, and validity periods. The sections below provide detailed information on the two most widely used categories (H-1B and L-1) and a brief overview of additional options.

H-1B visa: specialty occupation workers

The H-1B visa is the most common work visa category for skilled professionals joining US employers in specialty occupations. A specialty occupation is defined as a role that requires theoretical and practical application of a body of highly specialised knowledge and attainment of at least a bachelor’s degree or its equivalent in a specific field.

Eligibility requirements

To qualify for H-1B status, you must meet the following criteria:

• Hold at least a bachelor’s degree (or equivalent) in a field directly related to the specialty occupation
• Be offered a role that requires specialised knowledge in fields such as IT, engineering, mathematics, physical sciences, architecture, business, finance, medicine, law, education, or similar professional domains
• Have a sponsoring US employer willing to file the petition and comply with US Department of Labor wage requirements
• Demonstrate that the employer will pay you the prevailing wage for the occupation and geographic area

US Citizenship and Immigration Services (USCIS) evaluates both the role’s requirements and your qualifications to ensure the position genuinely requires degree-level expertise.

The H-1B cap and lottery system

Most H-1B petitions are subject to an annual numerical cap of 65,000 visas, with an additional 20,000 visas available for applicants holding a US master’s degree or higher. When demand exceeds supply (which has occurred every year since 2013), USCIS conducts a random lottery to select which petitions will be processed.

The H-1B lottery typically opens in March, with selected petitions processed for an October start date. This timing means planning your relocation at least six to nine months in advance is essential if your petition is subject to the cap.

Cap-exempt employers: Certain organisations are exempt from the H-1B cap, including institutions of higher education, nonprofit entities affiliated with or related to institutions of higher education, and nonprofit or governmental research organisations. If your employer qualifies as cap-exempt, your petition can be filed at any time without lottery participation.

Validity period and extensions

H-1B status is initially granted for up to three years and can be extended for an additional three years, for a maximum of six years. Extensions beyond six years are available in specific circumstances, such as when a permanent residence application (green card) is pending and certain processing stages have been reached.

H-4 dependent visas

Spouses and unmarried children under 21 may accompany you to the US on H-4 dependent status. H-4 visa holders can attend school in the US but are generally not authorised to work. Limited work authorisation is available for H-4 spouses if the principal H-1B holder has an approved Form I-140 (petition for permanent residence) or has reached certain stages of the H-1B extension process.

Dual intent provision: The H-1B visa permits dual intent, meaning you can hold H-1B status while simultaneously pursuing permanent residence without jeopardising your temporary status.

L-1 visa: intracompany transferees

The L-1 visa category is designed for employees of multinational companies transferring from a foreign office to a US office of the same employer. This category is commonly used for international assignments, executive relocations, and opening new US operations.

L-1A vs L-1B classifications

The L-1 category has two subcategories:

• L-1A: For managers and executives transferring to oversee operations, manage staff, or direct a key function or department
• L-1B: For employees with specialised knowledge of the company’s products, services, processes, procedures, or operations that is not readily available in the US labour market

Your role and responsibilities determine which classification applies. USCIS evaluates whether your position genuinely meets the managerial, executive, or specialised knowledge criteria.

Qualifying relationship and prior employment requirement

To qualify for L-1 status, the US entity and the foreign entity must have a qualifying relationship as parent, subsidiary, affiliate, or branch. Additionally, you must have been employed abroad by the qualifying entity for at least one continuous year within the three years immediately preceding your transfer to the US.

This one-year requirement means that L-1 status is generally not available for new hires. The employment must have been in a managerial, executive, or specialised knowledge capacity.

Individual L-1 vs blanket L petitions

Large multinational employers may qualify for a blanket L petition, which pre-approves the company to transfer employees without filing individual petitions for each transferee. If your employer holds a blanket L approval, your application process may be streamlined, with direct consular processing available in some cases.

Smaller organisations or those transferring employees infrequently typically file individual L-1 petitions on a case-by-case basis.

Validity periods

L-1A status can be granted for up to seven years total. L-1B status is limited to five years. Extensions are available in increments, but the total duration cannot exceed these maximums.

L-2 dependent visas

Spouses and unmarried children under 21 may accompany you on L-2 dependent status. Unlike H-4 dependents, L-2 spouses are automatically eligible to apply for work authorisation in the US through an Employment Authorisation Document (EAD), making the L-1 category particularly attractive for dual-career families.

Dual intent provision: Like the H-1B, the L-1 visa permits dual intent, allowing you to pursue permanent residence while maintaining L-1 status.

Other skilled worker visa categories

While H-1B and L-1 visas are the most common for corporate employees, several additional categories may apply depending on your qualifications, nationality, or the nature of your employment.

O-1 visa for individuals with extraordinary ability

The O-1 visa is available for individuals who have demonstrated sustained national or international acclaim in their field. This category has a very high evidentiary bar and is typically used for leading researchers, executives with major industry recognition, or professionals with significant awards, published work, or media coverage demonstrating their extraordinary ability.

O-1 petitions require extensive documentation, including letters from experts in the field, evidence of major contributions, and proof of recognition. If your qualifications meet this threshold, the O-1 offers flexibility in terms of employer changes and does not have an annual cap.

E-2 and E-3 visas

The E-2 treaty investor visa is available to nationals of countries with which the US maintains a treaty of commerce and navigation. This category is employer-specific and requires that the employer (or employee, in some cases) has made a substantial investment in a US business.

The E-3 visa is a specialty occupation visa available exclusively to Australian nationals. It functions similarly to the H-1B but is not subject to the annual cap, making it a faster and more predictable option for Australian professionals.

TN visa for Canadian and Mexican professionals

The TN visa is available to Canadian and Mexican citizens under the United States-Mexico-Canada Agreement (USMCA, formerly NAFTA). This category covers a specific list of professional occupations, including engineers, accountants, scientists, teachers, and management consultants.

TN status can be obtained relatively quickly and does not require a petition filed with USCIS in advance. Canadian citizens can apply directly at a port of entry, while Mexican citizens typically apply at a US consulate. TN status is granted in three-year increments with no maximum duration, but it does not permit dual intent.

The visa application process: what to expect

Understanding the application timeline and required steps helps you prepare for your relocation. While your employer and immigration counsel manage the legal aspects of the petition, you play an important role in providing documentation and attending interviews where required.

Employer petition filing

All employer-sponsored work visas require the employer to file a petition on your behalf. You cannot self-petition for H-1B, L-1, or most other employment-based categories. The employer files Form I-129 (Petition for a Temporary Worker) with USCIS, along with supporting evidence such as your educational credentials, employment history, job description, and documentation of the employer’s qualifying status.

Processing times and premium processing

Standard USCIS processing times for employment-based petitions range from three to six months, depending on the visa category and service centre workload. Employers can request premium processing for an additional fee, which guarantees a response within 15 calendar days. Premium processing does not guarantee approval, but it provides certainty on timing.

For H-1B cap-subject petitions, processing begins in April for an October start date. For non-cap petitions (L-1, cap-exempt H-1B, O-1), petitions can be filed at any time.

Consular processing vs change of status

If you are currently outside the United States, you will need to undergo consular processing once your petition is approved. This involves scheduling an appointment at a US embassy or consulate in your home country, attending a visa interview, and obtaining a visa stamp in your passport before travelling to the US.

If you are already in the US on another valid temporary status (such as a student visa or dependent visa), you may be eligible to file for a change of status to your new work visa category without leaving the country. Your immigration counsel will advise on the most appropriate approach for your situation.

Required documentation

You will typically need to provide:

• Educational credentials (diplomas, degree certificates, transcripts)
• Employment verification letters from previous employers
• Valid passport (must be valid for at least six months beyond your intended stay)
• Passport-style photographs
• Additional country-specific documents as required by the US consulate

Your immigration counsel will provide a complete checklist tailored to your visa category and individual circumstances.

Visa interview preparation

If consular processing is required, you will attend an in-person interview at a US embassy or consulate. The consular officer will verify your qualifications, the legitimacy of the job offer, and your intent to comply with US immigration law. Common questions include details about your role, your employer, your educational background, and your plans in the US.

Bring all required documentation in an organised manner, answer questions honestly and concisely, and be prepared to explain how your qualifications align with the position. Most interviews last 10 to 15 minutes.

MovePlus support: The MOVEPLUS™ platform centralises document collection, tracks petition status and timelines, and coordinates with your employer and immigration counsel to ensure all required materials are submitted accurately and on time.

Visa conditions and compliance requirements

Once your visa is approved and you enter the US, maintaining valid immigration status requires compliance with specific conditions and reporting obligations. Violations can result in status termination, removal proceedings, or future immigration consequences.

Maintaining valid status

Your work visa authorises you to work only for the sponsoring employer in the approved role and location. You cannot work for a subsidiary or affiliate of the sponsoring employer without an amended petition. Any material changes to your role, salary, or work location may require notification to USCIS or an amended petition.

If your employment is terminated, your authorised stay typically ends immediately or after a short grace period (if applicable), and you must depart the US or transition to another valid status.

Reporting requirements and address updates

All temporary visa holders must notify USCIS of any change of address within 10 days of moving. This can be done online through the USCIS website. Failure to report address changes is a violation of immigration law.

Travel considerations

To re-enter the US after international travel, you must have a valid visa stamp in your passport and a valid Form I-94 (arrival and departure record). If your visa stamp has expired but your I-94 and status remain valid, you will need to apply for a new visa stamp at a US consulate abroad before returning.

Travelling while a petition is pending (such as an extension or amendment) carries risks. Consult your immigration counsel before making international travel plans during pending applications.

Employment changes and amendments

If you wish to change employers, a new petition must be filed by the new employer. If your role, salary, or work location changes significantly with your current employer, an amended petition may be required. Your immigration counsel will advise on whether a change triggers the need for a new or amended petition.

Consequences of status violations: Working without authorisation, overstaying your I-94, or violating other visa conditions can result in removal from the US, bars on re-entry, and disqualification from future visa applications. Strict compliance is essential.

MovePlus support: The MOVEPLUS™ platform is designed to track visa validity dates, expirations, compliance requirements, and renewal timelines, helping employers stay informed of key deadlines and obligations.

Dependent visas: bringing family members

Most US work visa categories permit your spouse and unmarried children under 21 to accompany you on derivative dependent status. Dependent visa availability and work authorisation eligibility vary by visa category.

Derivative visa types

Each primary work visa has a corresponding dependent visa:

• H-4: Dependents of H-1B visa holders
• L-2: Dependents of L-1 visa holders
• O-3: Dependents of O-1 visa holders

Dependent status is tied to the principal visa holder. If your work visa expires or is terminated, dependent status ends as well.

Work authorisation for dependents

L-2 spouses: Automatically eligible to apply for work authorisation in the US through an Employment Authorisation Document (EAD). This makes the L-1 category particularly appealing for dual-career families.

H-4 spouses: May apply for work authorisation if the principal H-1B holder has an approved Form I-140 (petition for permanent residence) or has reached certain stages of the H-1B extension process beyond the initial six-year period. Otherwise, H-4 spouses are not authorised to work.

O-3 dependents: Not eligible for work authorisation.

Education access for dependent children

Dependent children on H-4, L-2, or O-3 status can attend US public schools and universities. They are typically considered international students for tuition purposes unless state law provides otherwise.

Common challenges and how employers can support

The US immigration process can be lengthy and unpredictable. Understanding potential challenges and your employer’s role in supporting you helps set realistic expectations and navigate complications effectively.

Visa denials and administrative processing

Not all visa applications are approved. USCIS may deny a petition if they determine the role does not meet the requirements, the supporting evidence is insufficient, or eligibility criteria are not satisfied. At the consular stage, visa officers may also deny applications or place them in administrative processing for additional security or background checks.

Administrative processing can add weeks or months to the timeline, particularly for nationals of certain countries or individuals working in sensitive industries. Your immigration counsel can advise on appeal options or alternative strategies if a denial occurs.

Requests for Evidence

USCIS frequently issues Requests for Evidence (RFEs) asking for additional documentation or clarification to support the petition. RFEs are common and do not necessarily indicate a denial, but they extend processing timelines and require careful, detailed responses prepared by immigration counsel.

According to USCIS data, RFE rates for H-1B petitions have ranged from 20% to 40% in recent years, depending on the employer and petition type. Thorough initial submissions reduce the likelihood of RFEs, but they remain a standard part of the process.

Country-specific backlogs and processing variations

Processing times and consular wait times vary significantly by country. Some US embassies and consulates have longer appointment backlogs than others, and applicants from certain countries may face additional security clearance requirements that extend timelines.

If you are pursuing permanent residence alongside your work visa, nationals of India and China currently face multi-year backlogs in certain green card categories due to per-country limits. Your immigration counsel can provide country-specific guidance.

The role of your employer and immigration counsel

Your employer is responsible for initiating and funding the visa petition process, as well as complying with all regulatory requirements such as prevailing wage determinations and attestations. Immigration counsel provides legal advice, prepares and files petitions, and represents the employer and employee in communications with USCIS and consular posts.

MovePlus supports the logistical and coordination aspects of relocation, including documentation management, timeline tracking, and communication between stakeholders. We do not provide legal advice but work closely with your employer and immigration counsel to ensure a smooth and compliant process.

MovePlus support: Through the MOVEPLUS™ platform, visa documentation is centralised, and key milestones such as petition, consular processing timelines and submission deadlines can be tracked when this information is provided by the immigration partner.  This coordination helps reduce administrative burden and supports better oversight of important tasks and timelines.

Pathways to permanent residence

Many temporary work visas permit dual intent, meaning you can hold temporary status while pursuing permanent residence (a green card). While this guide focuses on temporary work visas, a brief overview of employment-based permanent residence pathways is provided for context.

Employment-based green card categories: The US offers several employment-based permanent residence categories, including EB-1 (priority workers with extraordinary ability, outstanding professors and researchers, or multinational managers and executives), EB-2 (professionals with advanced degrees or exceptional ability), and EB-3 (skilled workers, professionals, and other workers).

PERM labour certification: Most EB-2 and EB-3 green card applications require the employer to obtain PERM labour certification from the US Department of Labor, demonstrating that no qualified US workers are available for the position. This process can take several months to over a year.

Country-specific backlogs: Due to per-country limits on permanent residence visas, nationals of countries with high demand (particularly India and China) may face multi-year waits for certain green card categories, even after approval of the underlying petition.

Permanent residence is a complex process that requires detailed legal guidance tailored to your qualifications, country of birth, and employment situation. Consult your immigration counsel to explore options and timelines specific to your circumstances.

Conclusion

Relocating to the United States as a skilled professional requires navigating a multi-layered immigration system with distinct visa categories, eligibility requirements, and compliance obligations. While the process can be complex, understanding the fundamentals of H-1B, L-1, and other employer-sponsored visa types helps you prepare effectively and set realistic expectations for your relocation timeline.

Your employer and immigration counsel are responsible for determining the appropriate visa category, filing petitions, and ensuring compliance with US immigration law. As the employee, your role is to provide accurate documentation, attend required interviews, and maintain valid status once in the US.

MovePlus supports organisations and employees throughout the relocation process by centralising documentation, tracking compliance timelines, and coordinating with all parties involved.
