Read the general professional work overview
Two professional employers each want part of your week. Prepare a separate record for each engagement instead of one combined description, because each one has its own duties, dates and employer. TN eligibility is assessed against a listed profession, the credentials that profession actually requires and prearranged professional employment. A single admission is not a general permission to perform work for whoever offers an assignment next, so ask which steps apply to each employer before either one is treated as settled. Responsibility here does not divide evenly. Each employer answers only for its own engagement, while you answer for the credential claim and for what you actually do across a week that neither employer sees in full.
Give each employer its own file
Build one folder per employer holding the signed offer, the described duties, the schedule, the start and end dates, the remuneration and the name of the person who can confirm those facts. Do not merge two schedules into one letter written by whichever employer answers first, because a reviewer cannot then tell which duties belong to which engagement. Where a record exists only in French, keep the original and note that a foreign-language document submitted to USCIS requires a complete certified English translation with the translator's statement of accuracy, completeness and competence. Record which documents already exist and which are still drafts. Name, for each folder, the person at that employer able to confirm its contents. A file with no accountable signatory is a draft, whatever it looks like.
Ask what each authorization actually covers
List, engagement by engagement, what has been requested and what has been granted. A filing, a visa, an admission and effective work authorization are distinct matters, and there is no universal rule that work for a second employer is permitted because something else is pending or approved. Hypothetical example: an applicant holds a countersigned letter from one employer and an email from a second describing two days a week starting later. Ask the person reviewing the file which step, if any, would apply to that second engagement, and what the answer depends on, before any work for it begins.
Test the profession, credentials and ownership separately
Each assignment must be examined against the listed profession and its specific credential requirements; the same person can fit one role and not the other, and the temporary nature of the intended entry is assessed as well. A degree from an institution outside Canada, Mexico or the United States requires a reliable foreign credential evaluation, which is a different service from translation and answers a different question. If either engagement involves an entity you own or control, raise it early: self-employment concerns sole or controlling ownership of the U.S. entity receiving your services, and control can exist below a majority interest. Adding a supervisor does not resolve that question.
