Translation also requires you to produce a style that is consistent with the source material. Professional translation is used to produce a similar quality document as the source material. If you translate english legalese into Spanish, you expect Spanish legalese output. Writing skills and specific domain experience is necessary. That is easier to achieve that level in your native language living in the target country. Nowadays, translator are rarely used for "meaning translation" ( like translating journal article for the managers ) as there is always some foreigner guy speaking that language and able to "explain" rather than translate the material. Except for less common language like Hebrew, Japanese, ... or big governmental organisations. BTW I think the requirement is reversed for interpretation. You need to be native of the source language, because you need to convey the meaning regardless of the form.
