Living in Frankfurt

Hello guys,

Well I'm 30 years old Portuguese and Peruvian citizen ( weird mix lol) Currently living in Portugal.
I have been in the USA for more o less 10 years where i finished my high school and part of University ( New Jersey).
Fluent in Spanish and English unfortunately my level in German is very poor but I am willing to learn.
Frankfurt is a city that called my attention when i went there couple years ago to visit a friend, ever since I always wanted to go there to live and prob establish my self. Why now? I just finish a small course of IT in Portugal and basically I don't want to wait any longer to go there.
As far as know education (university) is very accessible there so I want to finish my career once for all,
My main concern is if I would be able to find a job to get by without speaking German, I know i wont be easy at the beginning but according to my experience abroad everything gets even more complicated without an income right?

Best regards

Ovidio
