The L-1A visa is a temporary work permit available to individuals who are transferring to a U.S. company as either a Manager or Executive. In order to qualify for an L-1A, you must have worked outside the U.S. as a Manager or Executive for at least one year. You must have been employed by a parent, subsidiary or affiliate of the U.S. company. The L-1A can be approved for part-time or full-time employment and can be very useful in establishing and expanding a new U.S. business. Spouses of L-1A employees may also apply for an open work permit called an EAD card.
L-1A petitions are filed with a USCIS Service Center. Canadian citizens also have the option to apply directly at a U.S. port of entry, such as the Peace Bridge in Buffalo, NY. Port of entry cases are issued a same day decision.
L-1A petitions can be approved for up to 3 years at a time, for a total of 7 years. However, there are some exceptions that would allow you to extend your status for longer.
