[IWantOut] 23M Software Engineer Turkey -> USA

I am 23 years old male Software Engineer from Turkey. I have 7 years of hands-on experience in the domain of software development. I am working in the companies on my own country since i was 16. I know that I have to get a working visa or smt like that to live and start a new life in the U.S.A. but i don't how and where i can get it. I recently graduated from Bilkent University which is a good and known university in my country. I applied for jobs in the companies like Meta, Google, Amazon, Spotify, Snapchat etc. None of the accepted me and i thought that this is not the way. How can i find jobs in the smaller companies who will also support me for visa. I know that Master's degree is another option for starting a new life in the U.S.A. but i don't have enough money for education in the U.S. What would be your suggestions for me. Also i think that i am a good developer that i can catch any job related with the software but the biggest problem on my way is visa i think.
