The government fees are only the visible part. Confirm current petition amounts on the USCIS fee schedule, then budget separately for the corporate evidence the petition demands, which for a small or newly acquired U.S. entity is often the largest and least anticipated expense.
The expensive part is usually the evidence
Petitions in this class need documents that many closely held companies have never produced. Hypothetical example: a Saint-Cyrille-de-Wendover label-converting business acquires a small American finishing shop and budgets the filing fee alone; the petition then requires financial statements for a U.S. entity that has traded for four months, a valuation supporting the ownership claim, translated Quebec corporate records, and an accountant’s time to reconcile intercompany invoices — none of which appears on any government schedule.
Ask the adviser early for a written estimate covering corporate document preparation, translation, any premium processing you may elect, and the cost of responding to a request for evidence, which is a normal event rather than a disaster. It is worth being clear about what paying more does and does not buy: electing faster processing shortens a queue, it does not strengthen an organizational chart, and a file whose weak point is the qualifying relationship will simply reach that weakness sooner.
