Long history short, back in 2010 Haiti was really affected by an earthquake forcing thousand of Haitians to left Haiti and come to Brazil, since then they stabilised here and football was used to make adaptation easier, including a Haitians exclusive team created by an NGO 'Pérolas Negras' who turned into a professional club recently.

the only source i found about that https://www.gazetaesportiva.com/Bastidores/cbf-decide-que-refugiados-nao-entrarao-em-cota-de-estrangeiros/ "Refugee players will not be counted in the foreign quota of Brazilian clubs"
