How do I become a secretary for the FBI? Please help me...

I live in NYC and want to become a secretary for the FBI. Please help me.....

- Are they always hiring new secretaries?

- About how many secretaries work in the FBI building?

- Will they only hire people internally (please be honest)?

- I graduated from a university in California with a BA in psychology. Good enough?

- I have no experience as a secretary. However, when I was in high school, I was a volunteer for a congressman's office. Is that not good enough?

- Should I attend a secretarial school for the government?

- What suggestions/advice do you have for me to gain major advantage over other applicants?

I have no criminal background. I'm in my mid-twenties, female...Any tips and advice would be much appreciated. Thank you! Please help me.
