Read the general eligibility basics overview
Years of Canadian tax filings do not establish the Canadian or Mexican citizenship required for TN. Bring actual citizenship and Canadian status documents to the immigration review, and identify tax questions separately for qualified advice. Do not use a tax classification as a substitute for the facts a U.S. category requires. Bring the documents themselves to the first meeting rather than a description of them. A passport in hand answers a nationality question in seconds, while a summary of what someone believes their status to be generates a second meeting.
List status and nationality documents separately
On one list, put passports with their issuing country and expiry, any certificate of citizenship, and any pending citizenship application with its filing date. On another, put the Canadian permanent residence record, work or study permits, and provincial registrations. Notices of assessment, tax returns and payroll records belong to the second kind of question entirely: they describe how you are taxed, not what you are a national of. This ordering matters because nationality decides which categories are available at all. TN concerns Canadian and Mexican citizens, and Canadian permanent residence alone does not open it. Add a third list for anything that has changed and is not yet reflected on a document: a pending renewal, a name change, a citizenship application filed but not decided. Those items decide sequence, because a step depending on a document not yet issued cannot be scheduled from a date somebody hopes for.
Do not read a tax treaty as an immigration rule
If an adviser gives a tax-residency opinion, record which question it answers and do not treat it as an immigration authorization. Ask the immigration reviewer to identify the required nationality, employment or business conditions independently. Similarly, obtain tax advice on the actual move rather than assuming an immigration approval settles taxation. Give both advisers the same accurate dates and activities, while keeping their conclusions attached to the questions each was asked.
Sequence the two conversations
Hypothetical example: a person living in Longueuil holds Canadian permanent residence and citizenship of another country, has filed Canadian returns for a decade, and assumes that record makes them Canadian for a TN discussion. The immigration analysis turns on the passport actually held and on whether any other citizenship is relevant. Separately, a move raises real questions about Canadian tax residence, provincial coverage and the maintenance of permanent residence, and those belong to advisers competent in each. Bring both lists to the first meeting, along with the open question of which procedural steps — petition, visa, admission or change of status — would apply to you. Ask each adviser what they need from the other, and put that request in writing so neither waits. The most common delay in a two-adviser file is not disagreement but silence: each assumes the other has asked the question that neither has asked. Set a date for both answers rather than a date for the decision they feed.
