CGFNS in FLorida?

hi suzane! you've been very helpful to all of us here. i just passed the local boards here in the Philippines. And also plans to work there in florida hopefully in the next several years. As i have read in your forums, CGFNS is not needed in florida, only NCLEX. I was wondering why my cousin who works at a hospital in miami, florida is asking me to take the CGFNS exam ? i emailed her bout this but haven't got any reply yet. think she's too busy. i have submitted some requirements to CG and i plan to take them by nov. if i can make it through the aug. 10 deadline. if not, i might take it by march next year. also i plan to take the NCLEX by march next year , after several weeks after my CG.will that be advisable?

is the CGFNS exam applicable to other states? if in the future i plan to transfer to other states. by the way, what's the minimum years of experience needed before i get to work there?

sorry if i have too many questions. i have no one to ask here. this is the only and the fastest way i can get help. thank you so much!
