The sentence that sinks otherwise good postings
When we review engineering job descriptions from U.S. manufacturers, the pattern is consistent. The role is real, the plant is credible, the compensation is fair, and the duties describe work an engineer should do. Then, in the requirements section, one line undoes it: "Bachelor's degree or higher."
No discipline is named. No field of study is listed. To a hiring manager, that reads as flexibility. To a consular officer reviewing a TN application, it reads as a gap between the degree and the job. In one Tennessee metro area alone, we counted seven otherwise viable postings that carried this exact problem.
None of these postings was written carelessly. They were written the way most plants write them, for a domestic hiring pool where the degree line is a loose filter. The trouble starts when the same document has to support a visa application.
Why the degree line matters for a TN application
The Engineer category under USMCA (T-MEC) depends on a match between the candidate's credential and the work the role actually requires. Since June 2025, USCIS applies that test more tightly: the degree must be in a recognized engineering discipline, and degrees in computer science or software no longer qualify for the Engineer category.
That tightening changes how a job description gets read. A posting that says "Bachelor's degree or higher" leaves the officer with nothing to anchor to. A posting that says "Bachelor's degree in mechanical, industrial, chemical or a related engineering discipline" tells the officer what the employer believes the job needs, and it gives the candidate's title a direct line to compare against.
ACE & Bridgewell does not rule on TN category. Whether a role qualifies is determined by the employer's immigration attorney, or by the attorney engaged for the filing. What we can do is flag patterns in a posting early, before an offer goes out and before a candidate has spent weeks in interviews.
Three patterns that produce denials
Across the postings we review, three patterns account for most of the trouble. They are easy to miss because all three look normal on a plant floor.
The degree with no discipline
"Bachelor's degree or higher," "Bachelor's degree in a technical field," or "degree or equivalent experience." Each one leaves the required field open, and the last one invites a reading in which experience replaces the credential. For the Engineer category, that is the wrong signal.
Duties that read as supervision or inspection
A role can be genuinely technical and still be described as "oversee line operators," "perform visual inspections," "ensure compliance with work instructions" or "coordinate shift handoffs." Those are legitimate responsibilities. Written alone, they describe a supervisor or an inspector, not an engineer applying engineering judgement.
An open door for excluded degrees
Phrases like "or a related field" with no examples can be read to include degrees that no longer qualify, such as computer science or software. If the role needs an engineering discipline, name the disciplines.
How to fix the degree line
The fix is small and does not narrow your real candidate pool. It only makes the requirement match what you already expect.
| Version | Requirement line |
|---|---|
| Likely to cause problems | Bachelor's degree or higher |
| Likely to cause problems | Bachelor's degree in a technical field, or equivalent experience |
| Clear | Bachelor's degree in mechanical, industrial, manufacturing, chemical or materials engineering, or a closely related engineering discipline |
Name the disciplines that fit the work, in the order that reflects your plant. If a Quality Engineer in an injection molding plant realistically comes from industrial, mechanical, plastics or materials engineering, say so. Your attorney will tell you whether the wording holds up for the position you are filling.
How to write duties that show engineering judgement
The second fix takes more thought. The goal is not to inflate the role. It is to describe accurately the part of the job that requires an engineer. Most quality, process and maintenance roles contain real engineering work that gets buried under operational verbs.
Compare "inspect parts and report defects" with "analyze defect data to identify root causes, define corrective actions and validate process changes against specification." If the second version is true of the job, it belongs in the posting. If it is not true, the role may not fit the Engineer category, and it is better to learn that before recruiting begins.
- Lead with analysis, design, specification, validation, root cause and process improvement, where those describe the work.
- Keep supervision and inspection duties, but place them after the engineering duties and describe them as outputs of technical work.
- Name the standards, systems and methods the engineer will use, such as IATF 16949, FMEA, control plans, SPC or PLC troubleshooting.
- Avoid stretching titles. A posting that calls a technician role "engineer" invites the opposite problem.
Titles such as Project Manager or Operations Manager do not map to a TN category on their own. If the role is engineering-centric, the title and the duties both need to say so. Your attorney can advise on the wording.
A short checklist before you post
Run any engineering posting through these questions before it goes live, especially if you expect to hire from outside the U.S.
The degree requirement names at least one engineering discipline.
The requirement does not depend on "or equivalent experience" to fill the credential.
The first duties listed involve engineering analysis, design or validation.
Supervision and inspection duties are present but not the core of the role.
The title matches the actual work.
Your immigration attorney has seen the posting, the offer letter and the support letter before anything is filed.
Raise it early, not after the interviews
The worst time to discover a job description problem is after a candidate has been through several interview rounds and accepted an offer. At that point the fix means rewriting documents that were already shared, and sometimes it means telling a good engineer that the role does not fit the category.
If your own counsel handles the filing, that is a normal arrangement and many employers work that way. We still ask to review the posting, offer letter and support letter before submission. Not controlling the letters is not a reason to see them late. The TN itself is a consular process that takes roughly four months, so a fix made at the posting stage costs far less than one made after an offer is out.
