As you have already had exposure to foreign languages, I’m sure you know that bilingualism or multilingualism is commonplace in most of the world. Generally speaking, monolingual people, such as Americans, are outside of the norm. Because many nations have required foreign language learning throughout secondary education, there is a greater likelihood that many of the graduates will move on to achieve greater proficiency and fluency. Given that, having proficiency in a language is not necessarily enough to base a career on, although it can be. Generally, when we think of people with careers based EXCLUSIVELY on their language skills, we think of translators (written compositions from one language to another) or interpreters (simultaneous oral translations). Achieving a level of competence to become a full time translator or interpreter requires years of study and a better than average ability among proficient users of the language.
Now, using a foreign language within your chosen field of competence is another matter. There are legions of men and women around the world who use a second language at work simply for the job. LIke yourself, they may have found learning a foreign language to be fun or interesting in school and they took steps to achieve some level of competence such as studying or living abroad for a time (to acquire native like pronunciation and aural comprehension skills.) Perhaps then they chose a career which had some connection to that language.
Let me give a few examples from my own family’s life. I’m fluent in Japanese after moving to Japan after college and working in English education for 15 years. I’ve chose to live here because I like the people and the culture and I’ve acquired Japanese after years of hard work. My brother also studied Japanese in college, lived in Japan for a year and moved back to the states to work in the automobile industry. He now works for a major international auto parts supplier and uses his language skills when writing e-mails or occasional telephone calls with clients. Naturally, all of his clients are far more proficient in English than he is in Japanese, but it is a nice way for him to use his foreign language skill at work.
Although it depends on your other areas of competence, I would initially discourage you from thinking about linking your foreign language skill to a job. Language skills are simply another skill that you might bring to a job, unless you are already remarkably fluent. My brother’s son has grown up in a bilingual English/Arabic environment and will likely be 100% bilingual. However, I would never suggest that he pursue a job exclusively related to his language skills unless those skills were his only marketable ones. Examine your other strengths and interests to determine if a foreign language might be beneficial to any of them.
You didn’t give any details about your current level of education or what levels of competence you have already achieved in the foreign languages you have studied, so it makes answering your question a bit problematic. While Kimball’s answer about the State department is a legitimate one, there is a greater need to know more about your own personal and career goals before anyone could possibly give you advice on this matter.
How old are you? Which languages have you been exposed to? What levels of proficiency have you achieved? Where do you live now?
Are you finishing High School? University? Are you already in the work force?
Becoming proficient in a foreign language requires years of diligence and practice. There is a field called Second Language Acquisition which has studied how successful learners acquire fluency in a language. Joan Rubin, on SLA researcher has characterized 6 attributes of good learners. These strategic behaviors are tools that good language learners use. They are:
1) Good guessers.
2) Pay analytical attention to language form, but also to meaning.
3)They like to try out their new knowledge by “producing” in the the new language: speaking, writing, etc.
4)They monitor their own language production and that of others. (They notice how they make sentences and compare their own with that of native speakers.)
5) They constantly practice. (There are lots of ways of doing this!)
6) They cope well with feelings of vulberability for the sake of putting themselves in situations where they communicate and learn.
Do those sound like things that you do or would be willing to do to become proficient?
