Hypothetical example: a Nashwaak dairy technician has been told all his life that his mother was born in Maine, and he holds Canadian permanent residence through his wife. He has been comparing work categories. He should not be: if U.S. citizenship passed to him at birth then no category applies, and if it did not then his permanent residence supports none of them either. Settle the citizenship question before anything else is considered.
Citizenship through a parent is a legal question, not a family story
Whether citizenship was transmitted at birth abroad depends on the statute in force on the date of birth and on conditions such as the citizen parent's physical presence in the United States before that date, together with the parents' marital status at the time. Those conditions have changed repeatedly, so an outcome that applied to a cousin born in a different decade proves nothing about this case. An adult may document a claim through a U.S. passport application or, where appropriate, Form N-600; an original Consular Report of Birth Abroad is available only if the application is made before the child's eighteenth birthday. Gather the citizen parent's birth and physical-presence records first, because they are the evidence and are usually the hardest documents to find.
The answer changes everything downstream
A U.S. citizen cannot hold a nonimmigrant status and does not need one, and citizenship also carries obligations, including filing requirements, that a household should understand before celebrating anything. If citizenship did not pass, the analysis returns to the ordinary categories, and permanent residence in Canada does not help with any of them: the professional route under the USMCA is for citizens of Canada and Mexico, and treaty investment depends on the investor's own nationality and on the enterprise's ownership. Establish the citizenship position first, because building a professional or investment plan and then discovering the applicant was always a citizen wastes months and a good deal of money.
Sort the rest of the household separately
Whatever the answer for one person, everyone else is assessed on their own facts. A spouse who is a Canadian citizen has her own possible routes; a child's position depends on where and when that child was born and on the parents' status at the time, which may differ from the parent's own position. Where one parent turns out to be a U.S. citizen, the children's position should be examined immediately rather than assumed to follow automatically. Write the household out as a list with dates and places of birth, then deal with each line separately. That is slower than deciding as a family, and it is the only way the answers come out right.
