new passport but what about the visa

I just got my name changed on my passport and so they issued me a new one, however, my residence permit is still in my old name and isn't transferred in anyway in the new passport.  Do I have to carry around two passports when I fly or get jobs, or do I have to get my name changed on the visa too?

yep, just carry both passports with you when you need to travel...that's not a problem.  Same for when you need to show your visa to an employer, along with the documentation of the name change (ie marriage certificate, deed poll etc)
