A TN visa allows qualifying Canadian citizens to work temporarily in the United States in designated professional occupations under the Canada–United States–Mexico Agreement (CUSMA), the successor to NAFTA. Eligible professions can include engineers, accountants, management consultants, and other occupations listed under the agreement. Mann Law's cross-border immigration team advises professionals and companies on TN eligibility, supporting documentation, and filing strategy.

An L-1A visa is generally used for executives and managers transferring to a U.S. branch, subsidiary, parent, or affiliate of their company. An L-1B visa is intended for employees who possess specialized knowledge of the company's products, services, processes, procedures, or operations. Both categories generally require the employee to have worked for the qualifying related foreign organization for at least one continuous year during the preceding three years. Mann Law assists with L-1A and L-1B matters involving executive, managerial, and specialized-knowledge transfers.

Intra-company transfer categories, particularly the L-1 visa, are designed for qualifying executives, managers, and employees with specialized knowledge who are moving between related companies. These categories can provide a more appropriate route than other employment-based visa processes, but the company must establish the required qualifying corporate relationship between the Canadian and U.S. entities. Mann Law advises businesses on structuring these transfers and preparing the corporate and employment documentation required for the petition.

Yes. CUSMA contains professional-worker provisions that support qualifying cross-border employment between Canada, the United States, and Mexico. The U.S. TN category is available to qualifying Canadian and Mexican citizens, while Canada provides corresponding work authorization pathways for eligible U.S. and Mexican professionals under the same agreement. Mann Law advises individuals and companies on cross-border professional mobility in both directions.

Depending on citizenship and the nature of the business activity, the E-1 Treaty Trader and E-2 Treaty Investor categories may be available to qualifying entrepreneurs and investors. These categories can allow eligible individuals to enter the United States to develop and direct a qualifying enterprise or conduct substantial treaty trade. Mann Law's cross-border team advises entrepreneurs and investors on E-1 and E-2 filing strategy alongside the corporate structuring associated with the transaction.

Processing times depend on the visa category, filing method, government processing centre, and complexity of the application. L-1 petitions processed through standard channels may take several months, while premium processing may shorten the government review period for an additional filing fee where available. Requests for additional evidence can also extend the overall timeline. Mann Law prepares transfer applications with an emphasis on complete supporting evidence and clear documentation to help reduce avoidable processing issues.

Mann Law assists with Canadian immigration matters and coordinates with U.S. legal counsel where U.S. immigration advice or representation is required. This coordinated approach can be particularly important for corporate transfers, executives, professionals, and businesses operating on both sides of the border. Aligning Canadian departure or work authorization planning with U.S. entry requirements can help reduce unnecessary delays and inconsistencies.

TN authorization is generally tied to a specific employer and qualifying professional activity. A change of employer therefore normally requires new TN authorization or an appropriate filing before employment with the new organization begins. The correct process can depend on the individual's status, location, timing, and proposed employment. Mann Law advises TN professionals and employers on the appropriate filing sequence when employment circumstances change.
