You have to be admitted to the bar to practice law. Which is to say, other lawyers must recognize you as a lawyer, and this recognition can be taken away.

More practically, this means (in America) that you need a JD degree (4 year grad school), to pass an exam, and pass a(n oftrn horrifically thorough) character background check.

Minor point, but law school is only 3 years long.

I think they are asking about privileged communication
