Just received a RFE for my TN renewal. USCIS states "while the NAFTA does not allow for combination of classifications it does allow for concurrent employment through individual fillings". Then later in the RFE they state that "a TN nonimmigrant cannot hold dual job classifications". I have 2 degrees in different subjects (both are in the list of TN professionals and I am working for a small company that could use BOTH of my degrees). Nowhere can I find information that you cannot hold dual job classifications - or does this mean I must file 2 separate applications/renewals for each separate degree/job duty while working at the same company?
