can please anyone suggest a law school which take low fees for LLM courses. I want to Specialized in International law, European law and trade, commercial law

As the top law school are much costly for taking admissions and living in that place is also not cheap.

I don't have any work experience after College. Previously I had done Internship of 5 months during my vacation. does it will count under my work experience?

what will be the requirement of that College?
I am Planning for FU Berlin - MBL , europa institut Saarland University.

Any other Suggestions ?

Good choices. Maybe also the EMLE program? If you're an EU resident, the fees for that program are quite reasonable.

Hey!! I did my LLM Program at the Europa-Institut (Saarland) and I totally recommend it. I don't know what other masters you have been searching for, but this is a very complete one in many ways. First of all, semester fee is not that expensive (5600 euro for the whole year), because that price includes trips to Brussels, Luxembourg or Strassburg, and for example they took us to Berlin for 4 days only paying 150 euros. Secondly, the city of Saarbrücken is not expensive, prices at the Supermarket are very similar to the ones in Spain (where I come from), and renting a room in the city center varies from 280 to 350 per month. Also, transport is included under the semester fee, so you are able to travel within Saarland by train or bus.
About the requirements, Europa Institut just requires you to have a Law Degree or Bachelor and a B2 level in English, so no laboral experience is needed.

I Hope this can help you! Good luck ;)
