Get your education sorted out. Figure how you will pay for training and what is a realistic budget for flight training and living while training. Assuming it will take a bit of time to complete both, come to the USA and put eyeballs on several flight schools in FL and possibly other parts of the country. If your brother can make the time and is willing, bring him along to help decide the best option, re: schools and location.
Don't start a thread in the future with "Tell me how to live my life", pilots bust balls with such sediment. Good luck
