You can check whether your higher education entrance qualification is valid in Germany on anabin (Information portal of the Standing Conference of the Ministers of Education and Cultural Affairs).
If you come from a country outside the EU, you can contact the International Office of the university of your choice. If the university does not recognize your diploma, you will need to take a qualifying exam. Preparatory courses for this exam are offered by Studienkollegs across Germany. Alternatively, you can start your studies in your home country and transfer to a German university after completing your basic studies.
