Yes that's correct. They became my custodians in the first place was for me to continue to live in the state to keep my permanent resident card and ultimately naturalize and become a citizen here in the US. What about switching custodian guardianship to another family member (through marriage)? But the only thing about that is that the family member doesn't live in Florida, she lives in California.

And in doing that does she have to live in the state of Florida?
