Compare where you want to lifelive or travel. If you want to be in a bigger city like Berlin thanthen it is not important to speak German because almost everyone is kind of international there and in almost every community you find people from overseas or people who speaksspeak English. But if you want to travel through the country and visit the smaller villages and stuff like that you definitely need to have some kind of basic GermanyGerman skills.
P.S. What I also hear from many friends who speaksspeak only English and start to learn German, when you ask something in German (of course you have an accent) you mostly gettingget an English answer back. So don’t be upset with that. ;)
