Translation of swat in German

I remember that after highschool I went to study English in New York. First I did not know whether the city was right for me cause I wanted a place where I would not feel lost. However, it was the right choice.
I do translate to Spanish, but I always inform the client about my problem, in order not to have any dispute. The corrections I receive after proof reading are mostly a confusion between the different time forms in Spanish.
I once had a lesson with a private teacher, but unfortunately she could not come regularly. She was always sick, then I have visited a school in Andalusia, which was worthless, since we talked only German.
