No.
can you join fbi with type 1 diabetes?
No you can not become an FBI agent when you have gone to a juvenile facility.
they would become an FBI agent because of there income or probably they would just like to protect their community
YES
Be very inteligent
No FBI Director has ever become the US President, nor has any FBI Special Agent become the US President. President Nixon applied to become a Special Agent but was not accepted for this position.
All FBI agents are required to be US Citizens.
That is not a requirement.
FBI has their own SWAT team. Its called the HRT. Hostage Rescue Team. Its better than SWAT because FBI provides better benefits and better training. Along with Security to your house. They keep an eye on you to make sure you are ok. But if you want to downgrade from FBI to regular SWAT, just go to the police station and join their SWAT team.
Of course - many already have.
You probably need decent grammar :)
A really good one
