Filing charges are published in the USCIS fee schedule, Form G-1055, and vary with the forms used and whether premium processing is requested. The costs that are harder to predict are the professional ones: reconstructing the corporate chain, preparing staffing evidence, and answering a request for evidence about managerial capacity if the first submission was thin.
Pay for the evidence early or pay for the argument later
The predictable part of the budget is the petition itself and any expedited handling the group wants. Beyond that, three items regularly cost more than expected. Accounting work to document the relationship between the two companies can be substantial where ownership has never been formally minuted.
Legal preparation of the position description and the supporting staffing evidence takes real hours if the American operation is small. And a request for evidence questioning whether the role is primarily managerial consumes weeks of everyone's time, often at the worst point in a seasonal business's year. A small group can also underestimate the cost of the operational change the petition implies: if a supervisor has to be hired in Minden Hills so that Desmond's duties are genuinely handed over, that salary is part of the true cost of the transfer.
