Those associations are in CONCACAF but they are not in FIFA. They dont compete in the WC qualifiers. Something similar happens in Oceania with Kiribati, Tuvalu, Northern Marianas and other independent countriesWhat about the Concacaf French territories: Martinique, Guadeloupe & Guyane (French Guiana on the South American continent)? Do they have stadium models anywhere? They have enough players in the FIFA series to make national teams.
I'm happy with finishing the FIFA NTs. It has taken so long, and those stadium models cant be found anywhere. Pes 6, pes 21, rugby leagye, cricket, etc. Once done with them we may look for non FIFA independent countries or continental associations like Reunion and Zanzibar in Africa, Vatican City in Europe or French Guiana in South America, but for me FIFA associations should be the priority
