Canadian TN Visa applicants have the option of applying for a TN visa in person at a designated port of entry or by mail with U.S. Citizenship and Immigration Services (USCIS).  When deciding to process for your TN Visa at a port of entry there are many factors that must be taken into account. CBP Officers are very thorough and can be very intimidating. Once a TN Visa application is made the interviewing CBP officer will take notes of the interview in the system. Errors in a TN Visa application can lead to refused entry, future travel problems, and denials. Before presenting a TN Visa application at a port of entry is best to speak with a TN visa lawyer experienced in TN visa port of entry applications.  Due to our years of experience assisting Canadians with TN Visa applications and our frequent interactions with CBP officers, we are able to provide the most current and effective TN Visa representation available.
