That depends on the professional agreement. Ask whether the scope includes reviewing the notice, gathering additional records and preparing a response, and request a written estimate if it does not.
Separate added work from government fees
An evidence request should not be treated as proof that every case needs a new petition fee. Counsel should identify the actual procedural action and any current charge that applies. Translation, retrieval or extensive factual reconciliation may add professional expenses.
Business changes needed for future operations remain separate costs. Paying for a longer response or faster service cannot guarantee that the submitted facts meet L-1A requirements. Fee questions become answerable only after the scope of the response is known, which is why an estimate requested on the day the notice arrives is usually wrong.
Establish first which issues must be answered, then who inside the company will produce each record, then how much outside work remains. Translation, record retrieval and interviews with staff abroad move an estimate most, and all three surface during reconciliation rather than at intake. Hypothetical example: a museum exhibit fabrication business assumes its response is a drafting exercise until reconciliation shows that payroll records for the qualifying year sit with a former outsourced provider, at which point retrieval becomes the largest line.
Ask for a revised estimate once the fact-to-document map is complete.
