They serve different purposes. Identify the actual profession, institution and relevant evidence before commissioning services.
Keep preparation costs purposeful
Reliable foreign-institution evaluation, translation and practice authority are separate questions. A paid letter does not automatically satisfy any of them.
An academic evaluation may be unnecessary when the case relies on a permitted professional designation; if relying on a degree, check the issuing institution’s country and applicable evaluation requirement. For budgeting, distinguish credential evaluations, translations, professional help, travel and current government charges; consult the applicable official fee schedule instead of borrowing another applicant’s total. Canadians may generally request TN admission at a port of entry, while a US employer can use Form I-129 when suitable; those routes have different official charges and preparation needs, which should be checked against current government instructions. Ask the evaluation provider, in writing, what specifically they will compare and against what standard, because evaluations are produced to different specifications and one prepared for a general purpose may not address the comparison actually needed. Establish separately whether the awarding institution sits outside Canada, Mexico and the United States, because that single fact, and not the language of the paperwork, is what brings the evaluation requirement into play.
