Conifa - the Confederation of Independent Football Associations - says it would welcome a membership application from Jersey.
More than 2,500 spectators watched at Enfield on Saturday as Karpatalya - from a region of Ukraine - beat Northern Cyprus on penalties to win the alternative global tournament.
One of Jersey's Island Games rivals, the Isle of Man - playing under the Manx name Ellan Vannin - took part in the event, but withdrew over a row over player eligibility.
Its president, Phil Austin, has vowed to fight on, but any progress on that front is likely to take many years.
Conifa's general secretary Sascha Düerkop told ITV News the island could become a provisional member within months, if it meets Conifa's constitution.
Members must be football associations representing a 'people, nation, ethnicity, minority and geographically or sportingly isolated territory population'.
Applications are assessed by the CONIFA Executive Committee, which convenes monthly. If the Executive Committee voted to approve Jersey's prospective membership application, Jersey would immediately become a provisional CONIFA member. Jersey's membership application would be confirmed following the approval of a majority vote of the membership at our next Annual General Meeting held every January.
