Changing Jobs while on TN

Thanks for your reply. So, it is possible to obtain a new TN with a New Employer from within the U.S. while working for old employer and before leaving? Is this understanding correct?

Thanks,

Yes, generally that is the correct approach. However, different strokes for different folks does indeed apply here. Some resigning a position are more comfortable going back to the border to get a new TN with a new employer while others do not entertain such risks should they encounter a strict CBP inspector and may in fact prefer applying for new authorization from within the U.S. before making a move.

You can get a TN by mail, using I-129. This typically takes several months unlsee you pay $1000 premium (on top of the $300 fee).

So going to the border is always quicker and usuaully cheaper too.
