I would start out by contacting the Alabama Department of Conservation and Natural Resources. They can give you a definitive answer. Ask them what the laws and or licensing requirements are for native and non native venomous.
If a permit is needed, I would be surprised if you can't get it. Provided that you are 18 and can demonstrate some knowledge in the care for a venomous reptile.
