Read the general pathway comparison overview
Hypothetical example: a professional engineer in the Rural Municipality of Edenwold practises through a corporation she owns entirely, and a U.S. grain-handling company wants her on site for two years to design and oversee facility upgrades. Three routes present themselves. TN, because Engineer is a listed profession. L-1, if her corporation forms a U.S. subsidiary and transfers her. E-2, if she invests in and directs a U.S. engineering business. Each demands something different from a one-person corporation, and only one of them fits an engagement that is really a client relationship.
TN fits a client engagement, with one structural caution
Engineer is a listed profession satisfied by a degree or a state or provincial licence, and her Saskatchewan licence qualifies her. TN does not permit self-employment in the United States, but a Canadian professional corporation contracting with a U.S. client can support TN for its engineer when the U.S. company is the entity engaging the professional services and she owns no controlling interest in that U.S. company. The letter must come from the grain-handling company, describe the engineering services, the period and the pay basis, and be consistent with the contract her corporation signs. As a Canadian citizen she may apply at a port of entry without a visa stamp, or the U.S. client may file Form I-129. Practising engineering in the U.S. state may require that state's licence or an exemption. TD dependants may study but not work.
L-1 strains a one-person corporation
L-1 requires her corporation to own or otherwise have a qualifying relationship with a U.S. entity, both to remain actively doing business, and her to have worked for the Canadian corporation for a continuous year in a qualifying capacity within the prior three. The U.S. role must be primarily managerial or executive for L-1A or require special or advanced company knowledge for L-1B; L-1A is generally capped at seven years and L-1B at five. A new-office petition is initially limited to one year and must show premises and capacity to support the role. At a client site, an L-1B placement cannot be labour for hire and must remain controlled by the petitioner. A sole professional transferring to an entity that only bills her time may leave the Canadian corporation inactive and the U.S. office unable to support a manager. L-1 fits only if staff and real business continue on both sides.
E-2 fits a business, not an engagement
E-2 would require her to invest substantial, irrevocably committed and at-risk capital in a real U.S. engineering enterprise that she develops and directs and that will be more than marginal. A U.S. office with staff engineers, drafters and several clients could qualify, and her Canadian citizenship gives treaty nationality; treaty nationals must own at least fifty percent of the enterprise or she must otherwise have operational control. Her spouse would be employment-authorized incident to E-2 status, which TN's TD does not offer. But an E-2 built around one client's two-year project, with the investor as the only fee earner, is marginal on its face. No direct permanent-residence path follows from E-2. The choice follows the facts: a client engagement is TN, a corporate expansion with staff on both sides is L-1, and a personal investment in a multi-engineer U.S. practice is E-2.
