can i be a cna?

hello everyone! I'm considering becoming a cna because I'm new here in america and I just took my nclex and I think i failed it. I graduated bsn from my country but i feel like i cant use that unless i get license and if i fail then i dont have license so i need to earn money to take it again 'cuz i dont have a job right now and i feel lost when i look for job thats not related to nursing and cna is the closest one, so how do i become one? do i need to go back to school again? where do i get certified? thankk you..
