I don't know anything myself, but I believe there has been some discussion in a past thread. Hopefully it is helpful to your case. :)
What's your country ?
In some country you can enter directly in the bar school with an LLM.
In some other you need to do a Phd after your LLM for enter in the bar school.
After an LLM you can work directly like international lawyer.
