The Form I-129 fee, the fraud-prevention fee and the asylum program fee where applicable, all on the USCIS fee schedule, plus optional premium processing. Fees tied to the petition are the employer's cost.
Check the schedule and who is allowed to pay
Hypothetical example: The U.S. affiliate pays the petition fee for Form I-129, which varies with the employer's size and status under the current fee rule, together with the fraud-prevention and detection fee on an initial L petition and an asylum program fee unless an exemption applies. Premium processing is an optional additional fee. These amounts are published on the USCIS fee schedule and are revised periodically, so read the schedule on the filing date. Costs connected with preparing and filing the petition are generally borne by the employer and should not be deducted from Ines's salary. Her own costs are limited: L-2 applications for her family if they travel separately, certified translations of any non-English document, and moving. Because Ines is a Canadian citizen she needs no consular visa; a spouse or child of another nationality would pay a consular fee and need an appointment.
Hypothetical example: A food-safety traceability company sends its proprietary-platform specialist to assist a U.S. processor. The company should budget separately for the petition, fee categories that apply to its filing, translations, and preparation of technical exhibits. The most expensive error is often not a fee but a vague claim that leads to a request for evidence and missed commercial deadlines. A pre-filing review should test whether every technical assertion has a document behind it.
