Hi, does anyone here have any experience with getting a TN-1 visa for a post-doc?

I'm supposed to be starting a post-doc shortly and my new employer and I are trying to figure out whether I can get on a TN-1 visa for it. The potential problem I see is that I won't officially be done my phd (i.e. have a degree in hand) until the middle of August. I do have a B.Sc. and a M.S. already so I at least meet the minimum requirements for the visa. Any idea if this would be an issue? Also, have you experienced any problems with the exact title of your job not totally matching your degree (i.e. biologist is the applicable profession, but you have a phd in ecology or fisheries and wildlife)?
Thanks for the help.
