TN Visa for Environmental Engineer / Air Quality Professionals

Question: I can't seem to find a category under which Environmental Engineer/scientist and/or Air quality professionals are entitled for a TN-1 permit. I, therefore, will appreciate any post/advice/suggestions.

Reply: An Environmental Engineer or Air Quality position may qualify under the Engineer TN visa category. According to a legacy INS Memo, “all engineering specialties are included” for eligibility under the TN visa category for Engineers. INS – Cronin Memo (07-24-00).

The Occupational Outlook Handbook, a Department of Labor publication utilized by U.S. immigration officials as a reference tool for their occupational analysis, states that the Federal Government’s Standard Occupational Classification (SOC) system recognizes 17 engineering specialties, which includes Environmental Engineers. The OOH defines this engineering specialty as follows:

Environmental engineers develop solutions to environmental problems using the principles of biology and chemistry. They are involved in water and air pollution control, recycling, waste disposal, and public health issues…They conduct research on the environmental impact of proposed construction projects, analyze scientific data, and perform quality-control checks. Environmental engineers are concerned with local and worldwide environmental issues. They study and attempt to minimize the effects of acid rain, global warming, automobile emissions, and ozone depletion…OOH, Engineers (2008-2009).


Based on the INS Memo and OOH entry above, an Environmental Engineer or Air Quality position should qualify under the Engineer TN visa category
