The USCIS filing fee for Form I-129 and any additional statutory fees for the L classification, as listed in the G-1055 fee schedule, plus optional premium processing, legal fees and the family's own admission steps. The plant's operating budget is a separate matter.
Keep the petition budget away from the acquisition budget
The government charges for an L-1A petition are the I-129 filing fee and the additional fees Congress attaches to L petitions, all of which appear in the USCIS fee schedule and should be checked at filing rather than estimated from an older case. Premium processing is optional and priced separately. Professional fees for preparing the petition, translations if any Canadian record is in French, and the spouse's and children's own steps are further items.
None of this belongs in the plant's capital budget, and the acquisition price is not evidence that the company can afford to employ a manager. What the examiner does look for is that the U.S. plant can support a managerial position: staff on payroll, revenue or contracts, and a wage for the transferee.
Present those figures on their own schedule. A company that blends legal fees, purchase price and payroll into one number invites a request for evidence rather than an approval. Treat the immigration budget and operating budget as separate decision documents.
Hypothetical example: a Canadian manufacturer of fire-suppression nozzles acquires a U.S. distributor and budgets filing fees, counsel, warehouse rent, and the transferee's salary in one spreadsheet. Invoices settle the filing-cost question, while signed leases, payroll forecasts, and customer orders speak to the facility's ability to support the managerial role.
The business must decide whether it can fund both, because a paid petition does not demonstrate that the U.S. operation has the staffing or revenue the role requires.
