Regarding the new vote in the EU parliament, I wanted to know the affect on traveling in the EU if already possessing a visa.

For the case of already having a visa to enter one EU country, either long-term work or study, would there be a need to obtain another visa when entering another EU Country? (Ex. Possession of US Passport + German Work Visa, but want to visit France)
