Please I want to do my masters in international relations and diplomacy or criminology (maybe anything related to Law as well) as I have a degree in Law. Which country can I get admission easily without paying application fee and just applying direct to the school online.

I will really appreciate any useful information I can get. Thanks

You are looking for a lot, try Rwanda or Tunisia in African countries bit their admission is just for a token,
For Europe I think its Norway �� you pay admission fee but no Tuition fee is Tuition free.
