The employer files the petition and pays the I-129 fee, the fraud prevention fee, any applicable asylum program fee and optional premium processing, all listed on the USCIS fee schedule. Consular fees for non-Canadian family members and relocation costs are matters for the offer.
The petition is the employer's; the family's fees may not be
Because L-1A is an employer petition, the government charges attach to the company: the Form I-129 filing fee, a fraud prevention and detection fee, an asylum program fee whose amount depends on the employer's size, and premium processing if the employer chooses to buy a faster decision. Current amounts are on USCIS Form G-1055 and change. Legal fees for preparing the petition are ordinarily the employer's as well.
Hypothetical example: a Shannon logistics firm transferring its general manager to Texas should also decide, in writing, whether it covers the consular visa fee for her British-citizen husband, the certified translation of Québec documents, and the extension petitions in years three and five. Those are negotiable and often forgotten. Relocation, temporary housing and the costs of the manager's ongoing Canadian obligations belong in the transfer agreement.
None of the fees relates to the seven-year limit or to any later permanent-residence petition, which carries its own charges.
