Non-Immigrant Visas FAQs

The North American Free Trade Agreement (NAFTA) created special economic and trade relationships for the United States, Canada, and Mexico. The TN non-immigrant classification permits qualified Canadian and Mexican citizens to seek temporary entry into the United States to engage in business activities at a professional level. Among the professionals eligible to seek admission as TN non-immigrants are accountants, engineers, lawyers, pharmacists, scientists, and teachers. You may qualify for TN non-immigrant status if you are a citizen of Canada or Mexico, if your profession qualifies under the regulations, and if the position in the United States requires a NAFTA professional. You must have a prearranged full-time or part-time job with a U.S. company and have the qualifications to practice in the profession in question.
If you are a citizen or national of Australia coming to the United States to perform a professional “specialty occupation” assignment in the United States, you may be eligible for an E-3 visa. In order to qualify for an E-3 visa, you will need to provide proof of your Australian citizenship, bachelor’s degree, professional license (if required for the assignment by law), and information about the U.S. company and job. You may apply for an E-3 visa at a U.S. consulate abroad or request a change of status from USCIS. E-3 status may be valid for up to two years and may be renewed indefinitely. Spouses of E-3 professionals hold E-3D status. An E-3D beneficiary spouse can work in the United States incident to status. An E-3d beneficiary child is not eligible to work.
The H-1B1 program provides for the temporary employment of non-immigrant aliens in specialty occupations from Chile and Singapore, limited to 1,400 nationals of Chile and 5,400 nationals of Singapore. The H-1B1 program is governed by many of the rules that apply to the H-1B program. The period of employment is one year. Extensions may be obtained twice but only in one-year increments. Self-employment or being an independent contractor is not allowed. Applicants must show that they do not intend to immigrate.
Treaty Trader visas (E-1) and Treaty Investor visas (E-2) are non-immigrant visas for nationals of a country with which the United States maintains a treaty of friendship, commerce, and navigation. E-visas are for applicants who wish to go to the United States for one of two purposes: to carry out substantial trade, principally between the United States and the treaty country (E-1), or to develop and direct the operations of an enterprise in which the national has invested or is in the process of investing a substantial amount of capital (E-2). The Treaty Trader and Treaty Investor visas were established to facilitate and enhance economic interaction between the United States and other countries. U.S. immigration law explicitly states that E-1 visa holders must enter “solely to carry on substantial trade” and E-2 holders “solely to develop and direct the operations of an enterprise” in which they have invested. Moreover, these visas are non-immigrant visas and thus are temporary. Treaty trader/investor visas can be renewed or extended only if the investment or trade continues to meet all applicable requirements of U.S. immigration laws and regulations.
The L-1A classification is reserved for certain managers and executives. Executive or managerial capacity requires a certain level of authority and can consist of a mix of job duties. There are two main types of managers: function managers and personnel managers. Managers and executives plan, organize, direct, and control an organization’s major functions and work through other employees to achieve the organization’s goals. First-line supervisors, such as those who plan, schedule, and supervise the day-to-day work of nonprofessional employees, are not employed in an executive or managerial capacity, even though they may be referred to as managers in their organization.
The L-1B classification is reserved for certain persons having specialized knowledge. You may establish specialized knowledge by possessing either special knowledge, advanced knowledge, or both. Determining whether you have special knowledge requires a review of your knowledge of how the petitioning organization manufactures, produces, or develops its products, services, research, equipment, techniques, management, or other interests (or, in brief, its products or services.
To qualify for an O-1 visa, you must demonstrate extraordinary ability by sustained national or international acclaim or a record of extraordinary achievement in the motion picture and television industry and must be coming temporarily to the United States to continue work in the area of extraordinary ability. O-1 Extraordinary Ability visa status is reserved for those who are among the small percentage of experts who have risen to the top of their field. The approval of an O-1 petition by the United States Citizenship & Immigration Services (USCIS) decides whether an individual qualifies for O-1 classification. This classification requires a substantial amount of evidence. The O-1 is a very complicated visa category subject to high scrutiny by the U.S. government. Due to the complexity, the O-1 visa is used very infrequently.

I can't find enough words to thank Kim! She is so amazingly knowledgeable and helped me so much that I can't thank her enough. She answered all questions, gave invaluable advice, and I am so lucky that I had chosen her as a lawyer! Thank you again, Kim!

We cannot thank Kim and her team enough for everything she has done for us. From the very beginning, she went above and beyond with her time, guidance, and support. Her professionalism, knowledge, and compassion made all the difference in our journey, and we truly believe that without her help, the whole process would have been a lot harder.

What sets her apart is not only her expertise, but also dedication she shows to her clients. She always took the time to explain each step clearly, answer our questions thoroughly, and ensure we felt confident and supported throughout the process.

We are deeply grateful for her hard work and commitment, and we look forward to working with her again in the future if needed. We would gladly recommend her to anyone seeking legal help - Kim is, without question, the lawyer you want by your side.
Response from the owner:Thank you! Every attorney is thrilled to have clients like you who were on top of responding to emails.

Kim was a beacon of clarity during a frustrating and confusing process. I initially tried to file our marriage green card application on my own and only realized later that I had submitted just one of several required forms. I was overwhelmed and worried I’d make serious mistakes. From the moment we started working with Kim, everything changed. She answered all our questions with patience, simplified the entire process, and brought us peace of mind. She even met with us on Christmas Eve to help finalize our packet so we could submit it ASAP. When we got our interview notice, she responded quickly—scheduling a late-night Zoom call to walk us through what to expect and gave us a detailed checklist to stay organized. Thanks to her guidance, we felt confident and prepared—and the interview went smoothly. Kim is not just a knowledgeable attorney, but a kind and supportive person who genuinely cares about her clients. We’re so grateful for her help and can’t recommend her enough!
Response from the owner:Thank you for your kind words. You were truly a pleasure to work with. I don't routinely schedule to meet with clients on Christmas Eve or holidays in general. That said, your efforts were so sincere and I could not help but want to help you. Wishing your family much happiness.

Kim, Beca, and the entire team at Buhler Thomas Law were fantastic in our process of securing permanent residency, to say the least. From beginning to end, we received detailed, thorough, timely, and helpful communication about every step of the process. They were always quick to answer questions as well, but above all, we could tell that this team genuinely cared about us. The excitement we felt together as we reached each milestone of the process was tangible and means a lot. I cannot recommend this team enough for any immigration legal needs one might have.
Response from the owner:We have many wonderful clients that we enjoy working with. You two are among our favorites. We appreciate how responsive you bother were to our emails and calls. More importantly though we appreciate how helpful and kind you both were in how you both were in how you communicated. It truly was our pleasure to work with you.
