Hey Melina,
Welcome to our website. If your programme is in English language , you DONOT need any german language skills for your visa application.German embassy/consulate requires 6 banks of IELTS in this case. though once you are in germany , you would need basic german for day to day life.
Dont trust what consultants say , they dont work in the embassy or in the German government.
It is generally said that you wont survive in germany without german skills , this isnt actually the case , as i have seen many people without good german and have been living here. German’s are evolving and the young generation here can speak and understand english.
