the question is solved. thanks a lot!

You should ask JohnnyL (http://www.find-mba.com/about/johnnyl) about this. He seems to know the German bussiness school scene pretty well.

thx Malia, I also find that he seems to know the german business school scene well!!!
so I have asked him previously, i was replied that university of applied science has no international ranking.

I can underline that. Universities of Applied Science are 2nd tier universities in Germany. They have the academic level of commercial colleges.

Officially Fachhochschule has the same status of a 'higher education institution' as a normal university. The difference is that in a Fachhochschule you study for 4 years (instead of 5-7 that you have to study at a university to get a 'specialist' degree) and you have more field practice.

But companies like banks or consultants do not hire the Applied Science graduates, it's not the appropriate level of education.

Now when universities started to offer 4-years Bachelor degree companies in Germany are really confused, because they are accustomed to the longer educaton. So to get a good job in Germany you normally have to make a Bachelor+Master.

And - finally - it's pretty difficult to get a job in Germany if you are not a EU citizen. But with German education from a descent Uni you can get a job in England or somewhere else in Europe.
