Being fluent in spanish will get you a lot. The US is moving more towards being 50/50 when it comes to english and spanish. A lot of gov't agencies now require that you are bilingual in something because we are such a globally involved society.

On the other hand, having a BS now is almost equivalent to a HS diploma. Companies just kind of expect you to have one so, especially if you're not 100% on the exact career you want, you might to think about a generalized BS (like linguistics) and then go on to your masters when you are finished.

P.S. if it makes you feel any better, here is my list of majors since I graduated HS in 2005:

Video Production
Journalism
English/Education
Zoology (in which I went from pre-vet to pre-med, now I'm just a Zoo major)

Hardly anyone finishes in 4 years with the original degree they started with. And at the end of the day, you need to do what makes YOU happy. Your parents aren't the ones who will be in that career and doing that job for the rest of their lives. If you're still not sure, the best thing to do is probably to be undecided, take as many classes as you can in as many different subjects and find the one that really clicks with you.

Hopes this helps!
