The Form I-129 filing fee and the statutory additional fees for L petitions in the current G-1055 fee schedule, optional premium processing, professional preparation, and the spouse's and children's admission costs. The subsidiary's payroll for the transferee is a separate operating item.
Budget the petition, the family and the wage as three lines
The immigration budget has three parts that are easy to run together. The first is the government cost of the petition, made up of the I-129 filing fee and the additional fees that apply to L classifications, all listed in the USCIS fee schedule and subject to change. Premium processing is an optional addition.
The second is the professional work: preparing the knowledge narrative, assembling the technical evidence and, if any Canadian record is in French, certified translation. The third is the household: the spouse's and children's admission and any later extension. Separate from all three is the U.S.
subsidiary's obligation to pay the developer a wage appropriate to the role, which is an operating cost and also part of the evidence that the subsidiary is doing business. A company that asks the developer to bear the petition cost should put that in writing and take advice on whether such an arrangement is appropriate, since the petitioner is the employer, not the employee.
