Do not invent a universal requirement. For USCIS, the relevant rule requires full English translation and certification of accuracy, completeness and competence. Assess the actual process.
Pay for the task actually needed
A fee or seal does not replace the required content or establish eligibility.
Ask for four groups rather than one number: professional preparation and advice; government charges payable at the applicable step; third-party costs such as translation, document retrieval, courier, or a credential evaluation if one is needed; and travel. Foreign degrees from institutions outside Canada, Mexico and the United States require reliable evaluations; foreign-language USCIS submissions require complete certified English translations. Build a dated review file around the credential evidence, required evaluation or licence records, government-charge source, and the employer's actual duties. 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.
