The new employer needs a duty letter describing the actual proposed work, confirmation of the offer terms, and the applicant's relevant credentials for the new role. Even where the profession is unchanged, the new employer's own documentation is required rather than reused materials from the previous employer.
Prepare a complete, independent file
Ask the new employer to describe supervision, worksite, and expected duration in their own words rather than copying language from the prior offer. Gather updated credential evidence, since licensing or professional registration details may need refreshing depending on the state or the specific role. Keep proof of the current TN status and prior employer's letter available for comparison, since a reviewer will want to confirm the new role is genuinely distinct and properly supported.
