I got admission and I-20 from the US university but was refused the visa because of the situation in my country. i applied for visa from Pakistan where the US visa rejection rate is almost 98%
Now the problem is that since i was interested in mba from US, i didnt apply to any top tier UK universities. infact sheffield is the only option i am left with. Inlight of the situation its time i decide whether to go for sheffield or wait another year to apply to better schools.
My profile:
I am 25, have a BE degree with a little over 3 years of experience. IELTS 8.0, GMAT 700
PS. i want to change my career track, it could be operations, finance or management. one where i dont think my experience will make any difference.

Congrats....for your appreciable academic performance....Scoring 700 in GMAT is not a easy task.....I suggest you to wait for another one year and focus on top B-schools either in UK or US.....

You will not get any credibility for your GMAT score....if you go to Sheffield.
