Applying for H1B while being under TN status?

I do not believe that anything would happen to you or your status if the H-1B does not go through for you. You would still retain your TN status. On the question of travel, it depends upon how your employer is applying for your H-1B visa – is he/she asking for a change of status in the U. S. or for processing outside the country? The rule on change of status is that any travel outside the U. S. while the application is pending voids the change of status part of the H-1B application.
