Recently I have received a scholarship to study Criminal Justice in USA. I have faced Dilemma. Is that possible to apply for LLM in International Law in USA and Europe after receving Bachelor's in Crminal Justice?????

yes of course you can,,no problem about that,,,just let them know in your personal statement why you chose international law

Actually -- no. For most law schools, you must have a law degree prior to beginning the LL.M. -- so if you're studying outside of the US you'd need an LL.B. or licence or whatever it is called in your country. If you are in the US, you'd need a JD.

A US Bachelors degree will NOT permit you to study in an LL.M. program.

You can verify this by going to any LL.M. program's website and looking at the admissions requirements -- but trust me. This is how it works.

LLM Alum is right. In the US you will need to possess whatever law degree allows you access to the practice of law in your country (the degree that allows you to pass the bar, state exams, etc to become a lawyer.) So with a degree in criminal justice you will not be able to pursue an LLM in the United States because it does not allow you access to the law profession.

In Europe, however, there are several programs that do NOT require the applicant to possess a law degree. You can find more information on those programs here: http://llm-guide.com/article/213/llm-programs-for-non-law-graduates

You should also do a lot of independent research by looking at admission requirements of individual schools, and contact them directly if you have any question.
