What paperwork should I bring to Paris?

I'm going to Paris, France at the end of the week. What documents do I need to bring if I'm living in the UK and am here on a work permit

likewise,

I'm going back to the states for christmas with the bf... what should I have then? I'm assuming the boyfriend just needs his passport?

thanks,
jo

if you're living here on a work permit, you just need your passport to come in/out country.  no need for bank statements, work letter, orginal HO letter, etc... 

Yep, your passport is just fine provided that your permit is current.

When you re-enter the UK they may ask if you are still working at the same job.
