US Work Visa from Mexico
Working legally in the United States starts with choosing the right visa, and for citizens of Mexico, there are more paths available than many people realize, from the TN visa created specifically for Mexican and Canadian professionals to the H-1B, L-1, and seasonal worker categories used by employers across the country. Each comes with its own eligibility rules, application steps, and costs, and choosing incorrectly can mean months of lost time.
At Total Law, our immigration attorneys help both employers and individual workers navigate the US work visa system, from initial sponsorship through to renewals and, where appropriate, permanent residence.

Overview of US Work Visas
US work visas fall into two broad families. Nonimmigrant work visas allow a foreign national to work in the United States temporarily, tied to a specific employer, role, or program, while immigrant visas lead to lawful permanent residence, commonly known as a green card. Most people start with a non-immigrant category, and often transition to permanent residence if their circumstances and category allow it.
Most non-immigrant work visas require an employer to sponsor the worker in some form, whether through a formal petition filed with US Citizenship and Immigration Services or, in the case of the TN visa, a detailed job offer letter presented directly at the border or consulate. A few categories, such as EB-1 and EB-2 immigrant petitions, allow highly accomplished individuals to self-petition without an employer.
The benefits of holding a US work visa include lawful employment authorization, the ability to bring a spouse and children in many categories, and, for some visa types, a pathway toward permanent residence.

There are some limitations, as most non-immigrant work visas are tied to a specific employer and job, meaning a change of employer often requires a new filing, and several categories carry annual numerical caps that create real competition for a limited number of spots each year.
Recent policy changes have made the situation more complex. A September 2025 proclamation introduced a substantial supplemental fee for certain new H-1B petitions filed for workers outside the United States, and USCIS has moved to a wage-weighted lottery system for H-1B selection starting with the FY2027 cap season.

Types of US Work Visas
Understanding the different US work visa types is the first step toward choosing the right one. The right category depends entirely on the nature of the job, the worker’s qualifications, and, for Mexican citizens specifically, whether the role fits within the USMCA professional list.
Potential work visa routes include:
H-1B (specialty occupation worker). For roles that generally require at least a bachelor’s degree in a specific field, such as software engineering, finance, or scientific research. It’s employer-specific, subject to an annual cap of 85,000 new visas, and selected through a lottery when demand exceeds the cap.
L-1 (intracompany transferee). For employees of a multinational company transferring to a US office of the same employer, typically in a managerial, executive, or specialized knowledge role. The worker generally must have worked for the company abroad for at least one continuous year within the past three years before transferring.
O-1 (extraordinary ability). For individuals with a demonstrated record of extraordinary achievement in their field, whether in science, business, education, athletics, or the arts. It has no annual cap and no lottery, but the evidentiary bar is high.
TN (USMCA professional). Created specifically for Canadian and Mexican citizens under the United States-Mexico-Canada Agreement, this category covers a defined list of over 60 professional occupations, including engineers, accountants, architects, scientists, and registered nurses. Mexican citizens must obtain a TN visa at a US consulate before traveling, unlike Canadian citizens, who can generally apply directly at the border. There’s no annual cap, no lottery, and the process is often faster and less expensive than an H-1B, though it does not allow dual intent, meaning pursuing a green card while on TN status needs careful planning.
E-1 and E-2 (treaty trader and treaty investor). For nationals of countries with a qualifying treaty with the United States, allowing individuals to work in the US based on substantial trade or investment. Mexico has a qualifying treaty relationship that can support E-2 investor applications in certain circumstances.
H-2A and H-2B (temporary seasonal workers). H-2A covers seasonal agricultural work, with no annual cap, while H-2B covers seasonal non-agricultural work, such as hospitality, landscaping, and seafood processing, and is subject to an annual numerical limit. Both require the employer to first obtain a temporary labor certification from the Department of Labor confirming that US workers aren’t available for the role.
P and Q visas. P visas cover athletes, entertainers, and members of performance groups; Q visas cover participants in international cultural exchange programs that include an employment component.
R-1 (religious worker). For ministers and other workers coming to the US to perform religious duties for a qualifying nonprofit religious organization.
Each category has its own validity period, renewal rules, and restrictions, and comparing them side by side against your specific job offer and qualifications is usually the fastest way to identify the right fit.
General US Work Visa Requirements, Documentation, and Eligibility
US work visa eligibility varies significantly by category, but most applications share requirements such as:
- A genuine job offer or, for select categories, an independently demonstrated qualifying achievement
- Evidence that the applicant meets the specific educational, professional, or licensing requirements of the role
- A properly filed petition or application, whether that’s Form I-129 filed by the employer with USCIS, or, for TN applicants, a detailed employer letter
- Payment of the relevant government fees
- For most categories, an interview at a US embassy or consulate if the applicant is outside the United States
- Evidence of the applicant’s identity and, in most cases, a valid passport with sufficient remaining validity
Documentation requirements include the applicant’s degree and transcripts (with a credential evaluation if the degree was earned outside the US or Canada), a detailed job offer or employer letter describing the role and how it meets the visa category’s standards, evidence of any required licensure, and, for petition-based categories, the underlying USCIS approval notice before a consular interview can be scheduled.
US Work Visa Cost for Mexicans
US work visa costs vary by category and by who’s paying which fee, since some fees must legally be paid by the employer.
For petition-based categories such as H-1B and H-3, the employer typically pays a base filing fee of $1,015 for Form I-129, plus additional fees that depend on company size and whether premium processing is requested for faster adjudication.
H-1B petitions also carry fraud prevention and detection fees, and larger companies with a high ratio of H-1B and L-1 workers may owe an additional fee under recent legislation.
Certain new H-1B petitions filed for workers outside the United States are currently subject to a substantial supplemental fee introduced in September 2025, though this does not apply to most extensions or change-of-status filings for workers already in the US.
For the TN visa, Mexican applicants pay the standard nonimmigrant visa application fee $2,805 plus any applicable visa issuance fee based on nationality, since the employer does not file a separate USCIS petition for most TN cases.
For H-2A and H-2B categories, employers incur costs for the labor certification process, recruitment, and filing fees, in addition to the standard petition fee.
Workers may also need to budget for a visa application fee if applying from outside the US, a medical exam in some cases, and, for immigrant visa pathways, considerably higher costs associated with labor certification and the green card process.
How to Apply for a US Work Visa from Mexico?
If you are wondering how to apply for a US work visa status in a specific category, the process differs by category, but most non-immigrant work visas generally follow a similar sequence:
- Secure a qualifying job offer from a US employer, or, for TN applicants, obtain a detailed offer letter.
- The employer files the underlying petition with USCIS, where required (this step doesn’t apply to most TN applications).
- Once approved, or if the category doesn’t require a USCIS petition, the applicant completes Form DS-160 and pays the visa application fee
- The applicant schedules and attends an interview at a US embassy or consulate, unless already in the US and eligible to change status
- If approved, the applicant receives their visa and can travel to the United States to begin work
A strong application package will include a job offer that matches the visa category’s specific requirements, consistent information across all forms and letters, and complete supporting documentation.
Common pitfalls include vague job descriptions that do not match the visa category, missing or poorly translated documents, and gaps between what is stated in the petition and what is said at the interview.
Preparing early, ideally with input from an immigration attorney familiar with the specific category, meaningfully reduces the risk of delay or denial.
Sponsoring a Worker for a US Job
For most work visa categories, the sponsoring employer plays a central role and must meet various obligations.
Employers filing H-1B, L-1, or similar petitions must demonstrate they are a legitimate, operating business capable of paying the offered wage, and, for categories tied to a Labor Condition Application or labor certification, must attest to prevailing wage compliance and confirm the hire won’t adversely affect similarly employed US workers.
To qualify as a sponsor, an employer generally needs an active Employer Identification Number, a genuine job opening that matches the visa category’s requirements, and the financial capacity to pay the wage stated in the petition.
Employers must also maintain required records, such as the public access file for H-1B sponsorship, and respond promptly to any government requests for evidence or compliance reviews.
Sponsoring a foreign worker is not without its challenges. Annual caps and lotteries add uncertainty to categories like the H-1B, wage and recruitment requirements add time and cost to categories like H-2A and H-2B, and compliance failures can result in penalties, disqualification from future sponsorship, or, in serious cases, placement on the Department of Labor’s willful violator list.
Employers considering a sponsorship program, whether for a single hire or an ongoing talent pipeline, generally benefit from working with an immigration attorney to structure the process correctly from the start.
Legal Rights and Protections for Workers
Foreign workers on a US work visa are entitled to many of the same workplace protections as US citizens, including minimum wage and overtime protections under the Fair Labor Standards Act where applicable, protection against workplace discrimination under laws enforced by the Equal Employment Opportunity Commission, and safe working conditions under Occupational Safety and Health Administration standards.
Several visa categories carry additional, category-specific protections. H-1B and other Labor Condition Application-based workers are entitled to be paid at least the prevailing or actual wage stated in their petition, and employers who fail to do so can face Department of Labor enforcement action, including back wage orders and civil penalties. H-2A and H-2B workers benefit from specific protections around housing, transportation, and wage guarantees tied to their labor certification.
If a worker experiences a workplace violation, whether unpaid wages, unsafe conditions, or retaliation for raising a concern, the Department of Labor’s Wage and Hour Division is generally the first point of contact for wage-related issues, while the EEOC handles discrimination complaints.
Immigration status generally doesn’t prevent a worker from filing a complaint or pursuing a legal claim, and retaliation against a worker for exercising these rights is itself unlawful.
Anyone facing a serious workplace issue should speak with an employment or immigration attorney promptly, since deadlines for filing certain claims can be short.
Extending Stay and Changing Status
Most non-immigrant work visas allow for an extension of stay, generally requested before the current authorized period expires.
The employer typically files an extension petition with USCIS, and in many categories, the worker can continue working for up to 240 days beyond the expiration date while the extension remains pending, provided the petition is filed on time.
Extension eligibility and maximum total duration vary by category. H-1B status, for example, is generally capped at six years, with limited exceptions for those in the green card process, while TN status can be renewed in three-year increments with no fixed maximum, provided the underlying job and qualifications remain unchanged.
Changing status, meaning switching from one non-immigrant category to another without leaving the United States, is possible in many circumstances by filing Form I-539, or, for employment-based changes, having a new employer file a fresh petition.
However, this is not available for every situation. TN status, for instance, does not permit dual intent, so pursuing a change of status linked to permanent residence requires careful timing and advice.
A change of status must generally be approved before the worker begins activities under the new category.
Immigrant Visas for Working in the US
Immigrant visas differ fundamentally from nonimmigrant work visas: rather than authorizing temporary work, they lead to lawful permanent residence.
The employment-based immigrant system is divided into five preference categories, with roughly 140,000 visas available across all categories each fiscal year, subject to per-country limits that create longer waits for applicants born in high-demand countries.
- EB-1 covers priority workers, including individuals of extraordinary ability, outstanding professors and researchers, and certain multinational executives and managers. This category doesn’t require labor certification
- EB-2 covers professionals with an advanced degree or exceptional ability and often requires a job offer and labor certification, unless the applicant qualifies for the National Interest Waiver, which allows self-petitioning without an employer
- EB-3 covers skilled workers, professionals, and other workers, and generally requires both a job offer and labor certification
- EB-4 covers certain special immigrant categories, such as religious workers
- EB-5 covers investors who commit a qualifying amount of capital to a US business and create the required number of jobs
For most EB-2 and EB-3 cases, the process begins with PERM labor certification, where the employer must test the US labor market and demonstrate that no qualified US worker is available for the role, a process that can take more than a year even without complications.
Once certified, the employer files Form I-140, and the worker, once a visa number becomes available under the relevant category and country, files Form I-485 to adjust status, or attends an immigrant visa interview if applying from outside the United States.
Total timelines vary enormously depending on the category and the applicant’s country of birth, ranging from roughly a year for some EB-1 cases to several years or more for EB-2 and EB-3 applicants from high-demand countries.
H-1B Visa Requirements and Application Process
The H-1B is one of the most commonly used work visas. To qualify, the position must meet the standard for a specialty occupation, generally requiring a bachelor’s degree or higher in a specific field, and the applicant must hold that degree, or its recognized equivalent, along with a valid job offer from a sponsoring employer.
The process starts when the employer files a Labor Condition Application with the Department of Labor, attesting to the wage and working conditions for the role.
If the position is subject to the annual cap, the employer submits an electronic registration during the designated window, typically in March, and the case must be selected in the lottery before a full petition can be filed.
The employer then files Form I-129 with supporting evidence establishing the specialty occupation and the worker’s qualifications. Once approved, the worker either applies for a visa stamp abroad or, if already in the US in a valid status, may request a change of status instead.
Recent policy changes include the shift to a wage-weighted lottery for the FY2027 cap season, which gives higher-paid positions a better chance of selection, and the September 2025 supplemental fee for certain new petitions requiring consular processing, which remains a developing legal and policy issue. Employers and applicants should check the current guidance before filing, as both changes significantly affect strategy.
Green Card Application with an H-1B Visa
One advantage of the H-1B category is that it permits dual intent, meaning a worker can hold H-1B status while also pursuing a green card, unlike TN or most other temporary categories.
The typical application involves the employer requesting a prevailing wage determination, conducting required recruitment, and filing a PERM labor certification, followed by Form I-140 once certified, and finally Form I-485 once a visa number is available.
As PERM can take well over a year, and the full process is considerably longer for applicants born in high-demand countries, many H-1B workers begin the green card process years before their six-year H-1B limit approaches.
If the process is already underway by that point, specific extension provisions allow continued H-1B status beyond the normal limit while the green card case remains pending.
Common challenges include ensuring the PERM job description accurately reflects the actual role, managing employer transitions during a pending case, and navigating lengthy backlogs for applicants from certain countries, all of which make early planning especially important.
Family Sponsorship for Work Visa Holders
Most work visa categories allow the primary worker to bring a spouse and unmarried children under 21 as dependents, generally under a corresponding dependent classification, such as H-4 for H-1B holders, L-2 for L-1 holders, O-3 for O-1 holders, or TD for TN holders.
Dependents generally can’t work automatically; certain H-4 spouses may apply separately for employment authorization, but this requires a separate application and approval.
Family sponsorship involves sponsoring a relative for their own independent immigrant visa, is a separate process from these dependent categories and generally applies to US citizens and lawful permanent residents sponsoring qualifying relatives.
A work visa holder who later becomes a permanent resident or citizen may be able to sponsor family members through the family-based immigrant system, though this differs from simply bringing dependents along during the temporary work visa period.
The benefit of the dependent visa route is that it keeps families together during the work assignment but the limitation is that dependent status does not often include independent work authorization unless a specific exception applies.
Government Information and Resources
For authoritative, up-to-date information, the following government resources are the best starting points:
- USCIS (uscis.gov), for petition requirements, forms, and processing information for nearly every nonimmigrant and immigrant work category
- US Department of State (travel.state.gov), for visa application procedures, fee schedules, and reciprocity information by nationality
- US Department of Labor (dol.gov), for prevailing wage information, labor certification processes, and worker rights enforcement
- The US Embassy in Mexico City and its consulates (mx.usembassy.gov), for appointment scheduling and country-specific guidance for Mexican applicants
These sources should always take priority over general guidance when confirming current fees, forms, or eligibility criteria, since immigration policy in this area continues to change.

Frequently Asked Questions
For Mexican citizens who qualify, the TN visa is often the most straightforward, since it has no annual cap, no lottery, and a comparatively fast process, provided the job fits one of the USMCA’s approved professional categories and the applicant meets the underlying education requirements. Outside the TN category, ease really depends on the applicant’s field and qualifications rather than any single visa being universally easiest.
It depends heavily on the category. Non-capped categories like the TN, O-1, and most L-1 petitions can move relatively smoothly for well-qualified applicants with a genuine job offer, while capped categories like the H-1B involve real uncertainty due to the annual lottery. Seasonal categories like H-2A and H-2B depend on the employer completing a lengthy labor certification process before a visa can even be requested.
Eligibility depends on the specific category, but most require a genuine job offer from a qualifying US employer (or, for select categories, independently demonstrated extraordinary ability or investment), along with education, licensing, or experience that matches the role, and no disqualifying immigration or admissibility issues.
Total cost varies widely by category. Employer-paid petition fees for categories like the H-1B and L-1 can run from several hundred to several thousand dollars depending on company size and processing speed, while a TN applicant from Mexico generally pays the standard $185 visa application fee plus any applicable issuance fee.
Immigrant visa pathways involve considerably higher costs tied to labor certification, petition fees, and adjustment of status. Checking the current USCIS and Department of State fee schedules before applying is the most reliable way to budget accurately.
