Re-entry to the US.

Hello,

I'm currently residing the the states, on TN status.

I will be taking a trip back home to canada in the upcoming week, with a friend of mine who is of the opposite sex.

Is there any chance I will have trouble on my re-entry to the states?

I'm not sure what I would do to prove to them we're not romantically involved.

Thanks so much.

You shouldn't have any problem. TN Status allows exiting and reentering. It doesn't matter if you're romantically involved or not.
