hello, i m a foreign national from turkey. i am planning to opt for M.S and later phd in physics from a U.S.A university. i wanted to know :- 1) do ya have to pay to do M.S/phd or is there any scholarship/stipend programme available.(and if any stipend is paid to phd students approximately how much it is) 2) how much time does it take approximately to do both M.S+phd(i have an undergraduate degree in engineering -computer science) 3) what kind of jobs are available after doing phd-physics-and aproximately how much can one expect to earn after that. Thanks.
