Is it possible that after finishing LL. B, anybody can start practicing as a lawyer? I mean if he doesn't enroll in his native country's bar association, can he still practice? In case that is possible, does it mean that he acts as a solicitor not a barrister who can appear at court for argument?
A JD is very much NOT a PhD. The rough legal equivalent of a PhD is an SJD. All the SJD's I know personally were foreign and needed it for whatever they wanted to do (usually teach law).
