Hi, I am from India and I have got an offer of Phd in Engineering from Cambridge university (UK) with full scholarship. I am in a dilemma. I have been told by some that a Phd from US university would mean much better career opportunities than from UK (not withstanding the prestigious standing of Cambridge) . I am already 28 years old and to apply to US, I'll have to write GRE and wait until next year to start my Phd studies. What should I do? Should I go ahead and join Cambridge this year or write GRE, apply to US universities and wait until next year to start Phd next year?
