Non-Immigrant Work Visa Attorney

A non-immigrant work visa allows someone to work in the U.S. temporarily in a specific job, usually for one employer and for a set period of time (for example H-1B, L‑1, O‑1, TN, or E‑3). An employment-based green card grants permanent resident status, allowing the person to live and work anywhere in the United States indefinitely and eventually apply for U.S. citizenship, without being tied long‑term to a single employer or fixed end date. Many professionals start on a temporary work visa and later transition to an employment‑based green card as part of a longer‑term immigration strategy.Buhler Thomas Law helps clients navigate both the temporary and permanent pathways and plan strategically across both.

The firm assists clients with a full range of non-immigrant work visas, including H-1B (specialty occupation), H‑1B1 (for Chilean and Singaporean nationals), O‑1 (extraordinary ability), TN (Canadian and Mexican professionals under the USMCA), and E‑3 (Australian specialty occupation workers). The best category for you depends on factors like your nationality, job role, employer structure, and long‑term immigration goals. The immigration attorneys at Buhler Thomas Law can evaluate your background and identify the strongest available pathway.

Most non-immigrant work visa cases involve one to three months of preparation before filing, and we generally aim to file the petition at least six months before the intended start date to account for long processing times and reduce the need for costly premium processing upgrades. H‑1B cap cases follow a different schedule because registration takes place in March and the earliest possible start date is October 1. Buhler Thomas Law recommends contacting our office as early as possible to build a realistic timeline for your non-immigrant work visa in Salt Lake City or elsewhere in Utah.

If you are a citizen of Canada or Mexico, you may qualify for TN status under the United States‑Mexico‑Canada Agreement (USMCA), which allows certain professionals, such as accountants, engineers, lawyers, pharmacists, scientists, and  university teachers, to work in the United States temporarily. To qualify, you must be a Canadian or Mexican citizen with a prearranged professional job offer in a listed TN occupation and the required credentials, and you apply either at a U.S. port of entry if you are Canadian or through a U.S. consulate if you are Mexican. Buhler Thomas Law helps TN applicants and their employers navigate this process efficiently. Our immigration attorneys in Utah can assess whether TN classification is right for your situation.

Citizens of Chile and Singapore may qualify for the H‑1B1 visa, a U.S. work visa for specialty occupations that normally require at least a bachelor’s degree. This trade‑agreement category reserves 1,400 visas per year for Chilean nationals and 5,400 for Singaporean nationals, and these caps are rarely reached. Applicants usually apply directly at a U.S. consulate with a certified Labor Condition Application from a U.S. employer. H‑1B1 status is granted in renewable one‑year increments, does not allow self‑employment or independent contracting, and requires you to show that your stay in the United States will be temporary.”Buhler Thomas Law can walk Chilean and Singaporean professionals through the H-1B1 process and help compare it with other available non-immigrant work visas in Utah.’’

The O‑1 visa is for individuals with extraordinary ability who have earned sustained national or international acclaim in their field. You must be coming to the U.S. to work in the same area of expertise and be among the small percentage at the very top of your profession. Because USCIS demands extensive evidence and heavily scrutinizes these petitions, the O‑1 is generally suitable only for those with a truly exceptional, well‑documented record. The immigration attorneys at Buhler Thomas Law can review your credentials and advise whether the O-1 or another non-immigrant work visa better fits your situation. We serve clients in Utah and internationally, including those seeking immigration attorney services in Salt Lake City and throughout the state.

Many professionals hold a non-immigrantwork visa and pursue a green card at the same time.

The H‑1B and L‑1 are treated as dual‑intent categories, so you can go through an em

ployment-based green card process without normally jeopardizing your underlying work status. By contrast, visas like TN, H‑1B1, and E‑3 are technically “non-immigrant‑intent,” so green card planning must be more careful because strong evidence of permanent intent can create issues at future visa interviews or entries.Buhler Thomas Law can advise you on how pursuing permanent residence may interact with your current non-immigrantstatus and help you plan both pathways together.

non-immigrant work visas are temporary, but they are often an important first step toward a green card. H-1B visa allows dual intent, so you can work in the United States while your employer sponsors you for an employment-based green card, and L‑1 managers and executives may also transition to permanent residency, including through the EB‑1C category that can avoid PERM labor certification. Other visas such as TN, E‑3, and H‑1B1 require non-immigrant intent on paper, but are still commonly used while an employment based or family based green card process is underway. In some cases, time spent in valid non-immigrant status can also preserve work authorization and lawful presence while I‑140 petitions, PERM labor certification, or adjustment of status applications are pending. Buhler Thomas Law, P.C. helps clients coordinate their temporary work visa, long term green card strategy, and timing issues (such as quota backlogs and H‑1B max‑out dates) so that each move supports the next stage of their immigration journey.

In most employment-based non-immigrant categories, your spouse and unmarried children under 21 can apply for a dependent status (such as H-4 for H-1B workers, L-2 for L-1 workers, TD for TN workers, or E-3D for E-3 workers) so they can live with you in the United States while you are in valid status. Your dependents typically apply at a U.S. consulate abroad or, if they are already in the United States in another status, may file a change-of-status application with USCIS. Your spouse and children in dependent status are generally permitted to attend school, and in some categories, spouses may also be eligible for separate employment authorization. Buhler Thomas Law can review your family’s situation and help coordinate principal and dependent filings, so your family’s plans align.

Whether your spouse can work depends on your specific visa category and their dependent status. For example, certain spouses in L-2 or E-3D status are treated as employment-authorized incident to status, and some H-4 spouses may apply for an employment authorization document (EAD) if the H-1B principal meets specific green card milestones, while TD spouses of TN workers are not permitted to work in the United States. Because the rules differ significantly across categories and can change over time, it is important to understand which options, if any, apply in your case. Our immigration attorneys in Utah can explain your spouse’s work authorization options and help file the appropriate applications where available.

Most non-immigrant work visas are employer-specific, which means you cannot simply start working for a new employer without first taking legal steps to transfer or obtain new work authorization. Changing employers without proper authorization can jeopardize your current status and future immigration options. Buhler Thomas Law helps employers and employees evaluate timing, filing strategy, and risk when considering job changes on a temporary work visa.

Significant changes to your role, such as a substantial shift in job duties, a new worksite, or a promotion into a very different position may require an amended petition or new filing, especially for H-1B and L-1 workers. Smaller adjustments, such as routine raises or minor refinements in responsibilities, might not trigger a new filing, but it is important to confirm that your real-world position still fits the job description and wage level underlying your approved petition. Working in a materially different role than the one that was approved can create compliance issues for both you and your employer. Our attorneys can review proposed changes and advise whether an amendment or new filing is needed to keep your status secure.
