Recapture and maximum-period analysis is additional legal work on top of the petition, driven by how much history has to be reconstructed. Government fees are separate and should be read from the current USCIS fee schedule rather than from an earlier assignment's figures.
Two pieces of work, quoted separately
Ask for the period analysis to be scoped and priced on its own, because it has to happen first and because its result may change whether the petition is worth filing at all. A candidate with six months of eligibility remaining is a different proposition from one with four years, and no employer wants to learn that after paying for a full petition. The reconstruction of travel history can also be done largely by the individual at no professional cost, which keeps the legal time focused on the analysis rather than on data entry.
Where the employer is also weighing another candidate, this sequencing gives it a real comparison early. That comparison is worth having before anyone is promised anything, internally or externally. Hypothetical example: Rohan's employer wants him to transfer its proprietary industrial-dust-collection design standards to a new U.S.
team. The initial cost review should price evidence gathering separately from filing and travel, because technical records may need careful redaction or translation. A document inventory reveals whether the business already has usable manuals, access records and reporting lines, or must retrieve them from several sites.
Decide who approves disclosure of confidential material before a deadline approaches. Money is often wasted when the company buys speed but has not yet agreed what may safely be shared to prove the knowledge is proprietary and genuinely needed.
