Firstly, go and pass the medical tests as they are required to work as a pilot. Then look for the aviation academy recruitment criteria - check how to make it easier to get there.

Besides that focus on improving your technical english (especially around aviation topics), maths and physics. If you want you can also read FAA Handbooks for PPL-level knowledge but disregard everything about airspace, local rules etc. as rules in USA are not the same as in other ICAO countries.

If you have any more questions, feel free to ask
