<p>Fogcity- I don’t know what city you live in, but on the west coast speaking a second language is extremely marketable to many companies. Any of the BRIC languages are important. And while there are ‘many people who speak chinese/english’, that is entirely different than speaking english as a mother tongue, and fluent in mandarin.<br>
Learn Tibetan if you like, but the languages you are looking at take several years to learn, so budget your time.</p>
