The USCIS recently announced that beginning on October 1, 2012, its Service Centers will begin to accept Form I-129 Petitions for a TN Nonimmigrant workers filed on behalf of Canadian citizens who are outside the United States seeking admission as a TN Nonimmigrant. Previously, the USCIS only accepted Forms I-129 in connection with a request to extend a TN Nonimmigrant’s stay or to change a Nonimmigrant’s stay to TN classification. With this new Program, employers will have the option to either sign potential Canadian workers who are eligible for TN status apply for admission or to apply through a USCIS Service Center for preapproval of TN status prior to the worker applying for admission to the United States. Please note that this is only available for Canadian nationals and not Mexican nationals.
