No. Describe the intended activity and where it would be performed.
Keep the plan complete
A separate payer or client does not itself establish permission. Review all contemplated U.S. work rather than presenting only the most convenient part of the proposal.
Build a dated review file around the current statement of work, contracts, payroll identity, worksite list, and any business-ownership records. Create an activity chart identifying each Canadian and U.S. engagement, its payer, client, worksite, contract, and supporting original. Its practical purpose is to decide which activities are part of the presented employment and which are separate commercial work, rather than to collect papers with no stated issue. Hypothetical example: an urban planner has a U.S. municipal contract and also answers zoning questions for her own Canadian consultancy. Set the municipal contract beside the consultancy agreements and invoices to expose any work outside the presented employment. Trace each contemplated task to its payer and beneficiary, then decide which engagement the TN request would actually cover. A recurring problem is omitting the second activity because its invoices are issued in Canada. TN is limited to a citizen of Canada or Mexico who has prearranged duties in a listed profession and meets that profession's rule. A Canadian can request admission during inspection or preclearance; an employer can also use an I-129 petition with USCIS. Neither procedure authorizes U.S. self-employment. Refresh the document package if a client, billing route, location, or continuing Canadian assignment changes before the U.S. work begins.
