Mr Fletcher was moved to Honolulu earlier this week from American Samoa, after the courts there had dismissed charges of entering the territory illegally.
After that dismissal he was handed over to US federal marshals who took him to Honolulu.
Tonga has sought to have Mr Fletcher extradited and Assistant U.S. Attorney Larry Butrick has now filed an 8-page initial extradition request with the federal court in Honolulu.
He had sailed to Pago Pago after escaping from prison in Vava'u in September.
