International Visa Certificate

The U.S. Citizenship and Immigration Services (USCIS) has granted NBCOT approval to issue healthcare worker certificates to individuals coming to the United States to practice in the field of occupational therapy.

After initial submission and approval of the VCVC application, the VCVC certificate must be renewed every five (5) years if the certificant has not obtained a permanent visa or become a U.S. citizen.
For all the requirements, forms, and the application for the initial VCVC application, please download and carefully review the VCVC Handbook, located on the right sidebar.
