The petitioner pays the government fees, which are published and revised, plus the cost of establishing and documenting the U.S. entity. Untangling ownership records is often the largest internal cost.
Corporate housekeeping is the real expense
Read the current filing fees from the USCIS fee schedule at the time of filing rather than from a previous transfer, and treat faster processing as an optional business expense rather than an eligibility one. The costs that matter more here are corporate. Where several related companies exist, someone has to reconstruct the ownership chain, locate share registers that may never have been properly maintained, and have an accountant confirm what the intercompany arrangements actually were. Add incorporation of the U.S. entity, banking, premises, insurance and the financial statements needed to show both companies are trading. For a new office, add the cost of a second filing twelve months later, because the extension is decided on evidence collected during that year rather than on the original business plan.
Retrieving corporate records, obtaining certified copies from a registrar, translating foreign-language documents, reconstructing payroll history for the qualifying year abroad — each is priced by the hour or by the document, and each is worth scoping before it is commissioned.
