Hi to everyone!

Hi everyone! I'm a 36 years old mother of 3 new RN here in the Phil. I'm quite lost right now how to get to my dream of being a full pledged nurse in the US because i'm quite clueless how to get started. Could anyone give me any idea how to get started. I've tried to get an experience in hospitals here but since i'm already 36 it's quite hard! What then should i do next? Could passing the series of exams be enough to get started there? Thanks for taking time to read my message and more power to all!
