Study and live in USA

I am watre zibi robert michael, a Cameroonian of 21 year old. I speak and write both english and french. I did my primary and secondary studies here in cameroun. my diplômes are Odinary level and advanced level certificates, i am a graduated student since school year 2011-2012 were i schooled in a francophone university (universiter de yaoundé I). i could not make it because i did englophone education and i found it abit difficult to readapt to the francophone system. anyway i percevered, always trying to do other concours but with no succes because most schools here are francophone institutions. morover i am a scientist i wish to do mechanical ingeneering and here in my country there is scarce of such schools and the once present are francophone institutions. i therefor wish to go to the US in order to continue my studies and therefor do what i like. more still USA is anglophone speaking and so i will be more comfortable.
thank you for readind my demande and while waiting for your reply i wish you a great week.
yours faithfully watre zibi robert michael
