Hindustani & Arabic (Score 1)

Learn Hindustani (also known as Urdu or Hindi). It's the national language of both Pakistan and India, and is spoke by more than 900 million people, making it second only to Mandarin. But you should also learn Indian English (yes, there is an Indian English too). Indian English will serve you well in the entire Indian subcontinent. You'd also want to learn Arabic. The Middle East, specially places like Dubai, have a huge demand for IT these days. Be sure to learn Modern Standard Arabic and not a local dialect, as the dialectal variants of Arabic are nearly unintelligible to speakers of other dialects, but everyone understands Modern Standard Arabic. Arabic, with all its extremely diverse dialects, is spoken by about 400 million people worldwide.
