At least 18 years old you go threw training then about two weeks by then you will be able to do some pretty awsome stuff by the way I am going to one
25 years old.
You have to be 23 or old
You have to be 23 years of age and undergo 20 weeks of training.
Training is way more than 2 week, believe me. Also there is a cutoff age and that use to be 35. However I am sure this can be waived because you have to consider they hire military people and sometimes that isn't until they are 38 or 39. Work experience years are considered.
And what do you need to be an fbi agent?
