Hi Vinit,
If you are applying to a German university whose language of instruction is German then, of course, you have to know German language, a majority of the universities offer UG programs in German. Also, IELTS is compulsory.

Hi, depends on your academic grades not only on your IELTS.Your IELTS is no wonder very low but if your academics are strong you might get through and also a bridge course in English can be offered by the college.You should check the college and university websites for admission requirements.

Hi, depends on how much you scored in your Bachelor's degree, not on IELTS alone. Your IELTS score may be accepted or the university concerned may give you pathway course in English, it depends from university to university.

Hello,
Yes, chances are there. You may have to retake the IELTS, please check the score requirements on university websites and email them. A very strong SOP and excellent letters of recommendation from your professors, research work, publications etc. must be demonstrated.

Hello Nazia,
As of now, you are not eligible for an MBA in USA. Firstly, you haven't completed your Bachelor's degree, secondly you must gain work experience on completion of your degree and prior to the MBA application process. Additionally, you must take GMAT, thirdly your IELTS I am afraid is slightly low, but it can still be considered depending on the university. If you are keen for a management degree, you may consider MS Management instead. Also, keep note that most US universities require a four year Bachelor's degree.

Hi,if the medium of instruction was not English in your previous school or college or if English was the second language then you must take TOEFL OR IELTS, please check the requirements here
