An experience-based TN qualification needs evidence of real periods and relevant work. A client can describe an engagement without necessarily knowing the applicant’s entire employment history. Match each statement to the writer’s knowledge instead of asking every reference to repeat a five-year total. A practical first review should result in a dated evidence plan, a list of unsettled facts, and a decision about what must be resolved before money, travel, or work is committed. TN still requires the relevant nationality, listed temporary professional activity, appropriate qualifications, and a temporary purpose. The reader should separate facts already proved from assumptions that need a contract, official record, or individual advice.
Define the period the client can confirm
Hypothetical example: a client engaged a consultant for nine months but is asked to sign a letter describing five years of consulting experience. Ask the client to confirm the actual dates, tasks and relationship they know. Use other reliable records for the remaining periods rather than expanding the letter beyond its evidentiary basis. Hypothetical example: a sailcloth-pattern workshop adviser asks one former client to confirm six years of work though it saw only one redesign season. The concrete decision is whether to seek a narrow factual letter and use independent records for the remaining chronology. Record the document that settles the point, then preserve the earlier version if facts later change.
Connect the chronology to the listed alternative
For management consultant, the TN list accepts a baccalaureate or licenciatura degree, or documented equivalent professional experience of five years in management consulting or a specialty related to the consulting agreement. Explain relevance as well as duration. Canadian or Mexican citizenship, prearranged qualifying professional activities and temporary entry remain necessary. Build a chronology before drafting a summary. It should identify who knows each fact, when the record was created, and which evidence supports the next requested step.
Keep original records and explanations distinct
Support the chronology with contracts, work records and credible references. Identify gaps and overlap honestly. Foreign degrees from institutions outside Canada, Mexico and the United States require reliable evaluations; foreign-language USCIS submissions require complete certified English translations. Neither changes the dates of actual experience, and a newly written explanation should not be presented as a historical record. Do not use a commercial timetable as an immigration conclusion. Select a sequence that allows the underlying evidence and current official requirements to be checked before an irreversible action.
