I am an American citizen who is fluent in Mandarin Chinese. How can I make it big?
That is awesome! How foreward thinking! I am not sure what you mean by “make it big”, but you have great potential as a translator/interpreter at the UN or for a government agency. Also, working for an organization involved in international relations, or a firm involved in international trade, such as a big law firm or financial firm. If you are fluent enough, you could also work for a business that has need for bilingual people to work in various capacities.
