The Forester profession is written with alternatives: a baccalaureate or licenciatura degree, or a state or provincial licence. Either branch can satisfy the credential requirement, but the U.S. position must still be professional forestry work.
Two ways to prove the credential, one way to prove the job
Marc-Olivier can present either qualification, and choosing between them is a practical decision rather than a legal one. A forestry degree with a transcript that names the field is usually the cleaner document, because a licence raises follow-up questions about scope, currency and whether it remains in good standing. Whichever branch he uses, the credential answers only half of the test.
The other half asks whether the offered position genuinely requires and consists of professional forestry, and an officer may look past the job title on the letterhead. A qualified forester hired to run harvesting crews is still not performing a listed profession. If the employer wants an operations supervisor, the honest answer is that TN is the wrong category, and a different route or a redrawn role has to be considered before anyone books travel.
