Read the general eligibility basics overview
Hypothetical example: a machinist at a Centre Wellington equipment manufacturer holds a Canadian permanent resident card and an Irish passport. His employer wants to send him to a US customer site. TN is unavailable because it requires Canadian or Mexican citizenship, but Ireland is an E-2 treaty country and L-1 does not depend on citizenship at all. The deciding document is the passport, not the PR card, and the comparison changes completely once that is recorded.
Record nationality from the passport, not the address
Canadian permanent residence is a Canadian immigration status; it says nothing about citizenship. For US purposes the applicant's nationality is what his passport shows, and the household should write that down for every member before any route is considered. A spouse may be a Canadian citizen while the principal is not, which can reverse who should be the principal applicant. Children born in Canada are Canadian citizens even when their parents are permanent residents. Getting these facts onto one page is the single most useful step, because TN, E-2 and the treaty-nationality rule for E-2 ownership each turn on citizenship, while L-1, EB-5 and the Gold Card framework do not require Canadian citizenship at all.
Re-run the route comparison with the real nationality
For the Irish machinist, TN is closed regardless of how long he has lived in Centre Wellington or how well the job fits an Appendix 2 profession. E-2 is open in principle because Ireland has a treaty, but it would require him to be an investor or an essential employee of an Irish-owned enterprise, not a transferee to a Canadian company's US customer. L-1B may fit only if he has one continuous year of qualifying employment abroad within the prior three years, has company-specific specialized knowledge, and the active Canadian and US employers have a qualifying parent, branch, subsidiary, or affiliate relationship. Work at a customer site is possible only if the petitioning US employer controls the work and the placement is not labour-for-hire; L-1B stay is capped at five years. If none of these fit, the household should not assume a route exists; the Canadian citizen spouse's own qualifications may offer the better path.
Keep Canadian status intact while planning
A permanent resident who spends long periods in the United States risks failing Canada's residency obligation for permanent residence, and a pending citizenship application has its own physical-presence rule. Neither is a US immigration question, but both affect the household's options if the US plan fails or ends. Before accepting a long US assignment, the machinist should check the Canadian residency obligation and whether applying for Canadian citizenship first would change the US analysis, since citizenship would open TN. That decision has a timeline of its own and should be compared honestly with the employer's schedule. Do not let a US employer's urgency cause the loss of Canadian status that took years to obtain.
