For a foreign-language document submitted to USCIS, the translation must be complete and certified for accuracy, completeness and translator competence. A summary is not the same service.
Identify the required record before ordering the translation
Confirm which original documents the actual procedure needs, then obtain a scope covering their full content. Keep translation separate from the reliable evaluation required for a degree from an institution outside Canada, Mexico and the United States. Compare provider costs without asking them to omit material text. Verify government and professional fees separately.
Hypothetical example: An urban planner obtains several credential quotes before checking whether the selected TN category actually calls for the degree being evaluated. Start by identifying the government process, required identity and qualification evidence, and any translation or evaluation need. The first review should produce a document budget that separates public charges, translation, credential evaluation, courier, and professional services. Ask each provider what source material and revisions are included, because a low quote may exclude the pages that explain the qualification. Keep commercial invoices distinct from government receipts. Costs go wrong when an applicant pays for a broad evaluation that does not answer the relevant academic question, or assumes a customer's reimbursement will meet a government requirement. Confirm who pays each item and when the record is needed before ordering documents.
The budget should identify a stop point: do not order optional reports until the actual profession and procedure are settled. That preserves funds for the record that will genuinely be used.
