What do you need to do to become a spanish teacher in the US if you are a native spanish speaker ?

Hi my name is Mercedes, i am from Argentina and spanish is my first language. Right now i am studying to become a nurse and i will be done in a year, but i eventually want to become spanish teacher. Since i am already fluent in spanish, would i have to take all the courses to get my bachelors? I just want to know what is it that i need to do to become a spanish teacher, anybody knows how it works?

I used to go to a school, where the spanish teacher, someone I knew, was hired just because he was a native Puerto Rican and knew Spanish. He did not have any degrees in teaching, but was good with children. The school needed a Spanish teacher, which probably helped him, but I think there is not requirement. This was a private school, and rules might be different with public schools though. Though in these times, I it might seen that even if you were the most qualified person in the world, it might be hard to find a open slot, with people clinging onto their jobs. But right now most of the schools in my area always have an open spot for someone with this talent. Good luck.
