Hello I also been to the RAV today and would like to share my experince.
I was told that although I belongs to the same Canton, I should go to another RAV office which my village belongs to. So please double check with your germindehaus before you spend the time to visit a wrong RAV. I am not complaining just better make sure to save the headache.
The staff speaks no English but I speak very very very basic German so I can understand a bit. They gave me a map to the right RAV office and a sample registration form and telling me what to do next.
Then I call the right RAV office. No one speaks English but they are patient and helpful. I reconfirm with a staff by using German to ask her what I should bring to the RAV office, she said the 1st thing on my list should be "a friend who speak German". However, I still think it doesn't harm if you go there and take a look. Most RAV office situated just around the Bahnhof area.
I wrote a note about my situation and sayin that I want to inquire on training grant etc. I have it translated, so I think it is useful if you have something in German with you otherwise they really have no idea what you want. They are trying to be helpful but the language barrier is huge.
Just my experience, good luck to you all
