Hi mate,
I'm not sure about distance colleges in Germany but according to my research German colleges don't give admissions to Diploma holders especially Indian Diploma holders. And, you need to complete 13-years of education in order to take admission in Germany. You need to complete your 2nd-year of B.Tech in India then you can take admission in Germany. But for admission in Germany, you need to do a language perfection course like TOEFL or IELTS. After passing this exam, you will get your visa for Germany.
I hope this will give you an idea on how you need to apply for colleges in Germany.

Hello Riyaz,
You have raised a very interesting query. But unfortunately I think you can not do it since you would have crossed max age limit prescribed for diploma course. But I suggest you to approach your intended college to see if the college can grant concession to you about relaxation of age.

Hello Shubhangi,
Once you have taken admission in any branch, then perhaps it's possible to change branch in same college provided seats are available.

Hello Vikas,
It's very nice to see your dreams. There are very many design studios and Institutions in Europe. France and Italy see the two better known countries. But I suggest that you should approach a specialist agency dealing with this so that all nuances are taken care of.
