@aymen-m-taleb-gm , having gone through your post and the responses of my colleagues @xmasbaby0 and @Critter-3 , my questions are as follows :
(a) which country are you from / citizenship ?
(b) when did you enter the USA and with what visa ?
(c) did you receive any scholarship / grant / etc/ from USA or from any foreign entity?
(d) are you single / married ( and if married , then to whom -- US citizen / Resident / or ? )
(e) why do you think you have file a US return ( because you are a resident for tax purposes or ? )?
(f) do you have a tax-id ( SSN / ITIN ? ) ?
Once I hear from you I will circle back and help.
