Travelling to France for job purpose with German working visa for a week
I am currently working in Germany for a firm and for the purpose of getting some project requirement I want to travel to France, another office of the same firm for a week. I am currently having working Visa for Germany. Do I need anything else to travel for this purpose? I do understand that with schengen visa I am eligible to travel to France. But the purpose comes under job related. Does it make any difference? I am not going to get any salary from France for this journey, so my travel can be considered as a normal travel? Please clarify.
