I worked with a team that had a few Indians that migrated over and did online master courses to compensate for their Indian bachelor degrees. One did CSU Boulder's online course work, one did Phoenix Online, another did something else that I forgot.
All in all they still have trouble keeping up with the kids that came out of an American undergraduate college. They spent quite a penny for it too and spoke highly of it but now they make the same money as the rest of us despite none of us (I don't even have a bachelors) have advanced degrees.
From what I heard experiences Phoenix Online is wholly dependent on who you get as an instructor. Will it greatly impact your salary in the future? I don't think as much as good experience and good projects on your resume would.
