Translation of lifesaver in German

Thanks again for your time. I attached my avatar, it is very similar to the previous one. I have guided the development of the website, and I feel free to share my knowledge with others.
Basically, I would write an idea in English (or better in German) about Spanish Grammar or English Grammar and you could help editing it and translating it. I can send you emails with some remarks a little later or tomorrow. It is already 8.30 here.
Thank you for your message. Is it hard to get a visa for Germany? I am a nurse for children in a children's hospital in Chicago, USA. It is fascinating and exhausting at the same time.
