Has anybody done this?

I think it is impossible unless you have three years of studying in a common-law country.

BPP seems to be providing New York bar training in London as well as LLM. Check with them. http://www.bpp.com/courses/cpd--professional-development/law-1/new-york-bar-course.aspx

I have an LLB from the UK and I took NY last summer. Where is your first degree from? It says you must have an education of sufficient duration in a common law jurisdiction (which is typically three years). If you like, you can apply to the examiners for advance notice of eligibility, and they'll give you a certificate thing you can send in with your application to take the exam.

You can also cure a substantive or durational deficiency by legal study in the States, meaning that LLB candidates from civil law countries usually take a U.S. LLM and then sit the Bar.

Yes ive heard this too,,,you have to study your LLM in the States and take the bar exam

That's true for some states in the US only right know I can only remember NY and California, but other states may accept this as well.

It's relatively easy to be admitted to the NY Bar or Cali Bar (though the latter is quite a tough exam), but actually putting the credential to use is quite another matter.

I think an LLM from a UK university wouldnt do you much if what you wanted was to sit for the NY bar exam. Im pretty sure only an LLM from US universities would allow you to skip a JD and sit for the bar
