Government filing fees per the USCIS fee schedule, Form G-1055, depending on the forms and employer size, with optional faster processing at extra cost, plus professional fees and the internal hours needed to document the specialized knowledge and prepare the American position description.
Compare the petition against hiring locally
Before spending, cost the alternative honestly. What would it take to hire an American engineer and train them on the company's system, including the time the specialist would spend teaching rather than delivering? For some manufacturers that is the better long-term answer, since it builds capacity in the subsidiary and does not consume a five-year allowance. For others, the installed base cannot wait and the transfer is the right decision. Either way, budget the documentation hours realistically, add legal review of any customer contract the petition will reference, and confirm current government fees at the time of filing. The comparison itself is worth doing even when the answer is obvious, because it usually surfaces the training plan the subsidiary needs regardless.
Hypothetical example: a Tyendinaga company developing marine-navigation sensors sends its sole firmware specialist to its U.S. affiliate. Beyond filing fees, the business should price the knowledge-transfer plan: replacement coverage in Canada, secure access, travel, and onboarding abroad. Document why the assignment produces a business benefit rather than simply filling a vacancy. If the financial case depends on uninterrupted remote work by the transferee, check whether the proposed duties and location still match the petition. A cost schedule linked to the deployment plan can reveal when a shorter visit, additional hiring, or a different assignee is commercially sounder.
