Read the general life across the border overview
When two routes both appear workable, such as TN and L1, or E2 and an immigrant investment route, the comparison needs a structured framework rather than a preference for whichever seems faster. Each route has its own eligibility test, its own durability, and its own consequences for dependents.
Build a comparison table of legal requirements
List what each route actually requires: TN needs a listed profession and matching credentials, with no self-employment allowed; L1 needs a qualifying corporate relationship, prior qualifying foreign employment, and a genuinely executive, managerial, or specialized-knowledge role; E2 needs treaty nationality, a qualifying at-risk investment, and a controlling or developing role in a non-marginal enterprise. Confirm which requirements are already met and which still need to be established before comparing anything else. Put the requirements in a table with one column per route and one row per condition, and fill it in with documents rather than impressions. The professional route needs a listed profession, matching credentials, and no self-employment. The intracompany route needs a qualifying corporate relationship, the year of qualifying employment abroad, and a genuinely managerial, executive, or specialized-knowledge role. The treaty route needs nationality, capital at risk, and control of a more than marginal enterprise. Mark each cell met, obtainable, or absent.
Compare durability and dependent consequences
TN status is renewable but has no built-in path to permanent residence. L1 can support a later employment-based petition depending on the role. E2 has no automatic route to a green card. Each of these has different implications for a spouse's work authorization and for children approaching 21, so weigh the family's timeline against each route's structure, not just the principal applicant's eligibility. Hypothetical example: a household includes a seventeen-year-old and a twenty-year-old, which changes the weighting entirely. Derivative eligibility generally depends on being unmarried and under twenty-one, so a route whose decisive step is three years away affects the two children very differently. Add a row to the table for each family member, and note what each route offers a spouse in terms of employment authorisation, since that answer differs between categories and is more often assumed than checked.
Weigh the sequencing, not just the label
One route may be usable now with a genuine option to pursue the other later, while the reverse sequencing may close off options. Decide based on how the two routes interact over time, and confirm each one's current requirements before committing, rather than choosing the category that sounds fastest. Read the table across time rather than as a snapshot. One route may be available now while leaving the other open later, and the reverse sequence may close options that cannot be reopened. Ask which choice preserves the most alternatives if circumstances change, and confirm each route's current requirements before committing rather than relying on a summary written for a different family. Record the reasoning so the household can revisit the decision without starting over.
