Question

Traffod moved to Washington D C to work as a researcher for National Geographic magazine.
I don' like the sentence below, too complicated , too long,is there a better way to translate this.
Trafford se mudo a Washington D C para trabajar como investigadora de la revista National Geographic magazine. Should, I translate National Geographic into Spanish? What is the rule about proper names, should one changed the name of a business or organization into the language the whole paragraph is being translated'

Answer 1

It's a correct translation:
Trafford se mudó a Washington D.C. para trabajar como investigadora de la revista "National Geographic". magazine.
In my opinion i wouldn't change the proper nouns (for specific people, places, or things).
