I am going to get Rosetta Stone to further my language skills. I know there is a Japanese and Mandarin Proficiency Test Available in the Tri-State Area so I can eventually get certified after my Associates. However, my question is, what language should I focus on (Spanish, Mandarin, Japanese, and Hebrew) to give me an advantage in Philadelphia? Rosetta Stone does not offer Cantonese. (Which is stupid!) So, besides that and Spanish, what secondary language would be a great asset in the job market for Philadelphia County?
