undergrad in U.K. grad school in US

<p>Hello,</p>

<p>I am studying political sciences at Oxford in the moment. I will graduate next year and thought about applying to a grad school in the US for a m.phil/phd. </p>

<p>Do you know which british degree classification is needed for an M.Phil. at an Ivy League school? The system being First Class, Second Higher etc. </p>

<p>I would rather finish the M.Phil at Oxord and woudl go on to the U.S. afterwards (if I have chances). But how are the chances fro U.K. graduates to geta ccepted in the U.S. Is Oxbrdige an advantage?
In terms of graduate applications, do the U.S. unis still put emphasis on Ec's?
I read some posts in the forum and many already completed research experience before they applied to grad school - this is highly in the U.K. as you normally gain the M.phil. after oen year and the phd after 3 years. So do I have to work in industry after the M.Phil. to have 'enough' experience for applying to a Ivy Leauge grad school?</p>

<p>help is appreciated,</p>

<p>Tim</p>
