Department of State in a Liaison Meeting on October 6, 2016 announced that a TN visa is not employer specific.
DOS takes the position that if the TN worker changes employers, the TN visa remains valid until it expires or is revoked.
When a worker changes employers, however, DOS suggests that the TN worker should keep the I-797 approval notice for their records, and in case it is requested by a Department of Homeland Security official.
