What does a "Seminole Sovereign Nation" mean?

Question

Does it mean that a Seminole does not abide by the Floridan law?

Is that sovereignty restricted to the Seminole reservation or also outside?

Answer 1

It essentially means that. It is a nation that declared independence from the United States.
The Seminoles are the only American Indian tribe never to sign a formal peace treaty with the United States.

The Seminole Tribe of Florida and the Miccosukee Tribe of Indians of Florida entered into agreements with the US government in 1957 and 1962, respectively, confirming their sovereignty over tribal lands and agreeing to compensation for seized territory. Since then, the tribes have developed an economy based largely on sales of duty-free tobacco, tourism and gambling.
Their sovereignty is restricted to the reservation. They are subject to Florida state law if they commit a crime outside of the reservation as was the case of Kirk Douglas Billie who drowned his children in his SUV and was tried and convicted of manslaughter in 2004

Answer 2

They are considered their own entity. Meaning they have their own rules and laws they abide by. I think that it is restricted to members of that tribe that have a certain precentage or higher of Seminole Blood and probably to within so many miles of the reservation.
