IN THIS GUIDE · Identifying the real employer and work relationship when a professional employer organisation handles payroll
Start with the TN eligibility and application overview
Identify the entity that directs the professional work
Ask who sets the applicant's duties, assigns projects, reviews performance and decides whether the position continues. That is normally the operating company, even where a third party issues pay statements and administers benefits. Get the answer from the hiring manager rather than from the onboarding portal, because the portal reflects the payroll arrangement and says nothing about who the professional actually works for.
Decide whose letterhead the supporting documents belong on
A support letter should come from the entity that can genuinely describe the position: the profession, the duties, the qualifications required, the expected period and the terms. A payroll provider can confirm compensation and administration, and that confirmation is useful, but it is not a substitute for a duty description from the company directing the work. Both documents can be provided together where the arrangement warrants it.
Match the arrangement to the route being used
Where a petition is used, have counsel identify the appropriate petitioner from the actual agreements and employment facts. Do not assume either that the payroll provider must be the petitioner or that it can never have a relevant employment role. Keep petition approval, admission and effective work authorization distinct; a filing alone is not universal permission to begin work.
Check ownership and intermediaries in the structure
Layered arrangements sometimes conceal an ownership question. Sole or controlling ownership of the United States entity the professional supplies services to is treated as prohibited self-employment, and routing payroll through an outside organisation does not change that, nor does nominal independent supervision. Contracting structures are not prohibited as a class, but a structure this specific should be reviewed by counsel with the actual agreements in hand.
Line up the three terms that expire on different dates
The service agreement between the payroll organisation and the operating company, the engagement of the professional, and the period authorized for that professional each run on a separate calendar, and none of them renews the others. Ask for the expiry date of the agreement between the two companies before a start date is fixed, since a lapse partway through the authorized period can change which entity is administering anything at all. Where the role is funded from a budget approved for one fiscal year, ask what the next approval cycle is expected to do with it; a requested period that quietly assumes uncommitted funding is awkward to defend when an extension is considered. Hypothetical example: a management consultant is engaged to redesign production scheduling at a sawmill, with pay administered by an outside organisation whose contract with the mill expires in four months. Rather than request a period outlasting that contract, the parties fix the requested period against the engagement letter the mill signed itself.
