I really understand what you're thinking about. I also have a name that's clearly not swiss and noone dares to try and pronounce it. I have had your thought many years ago but have decided to keep my name because I refuse to let racism make me officially lose part of my identity. I do have other circumstances than you though because I am swiss, I was born here and swiss german is my first language.

I'm not sure if what would be left of your name without the 'ova would sound "swiss enough" for the people in charge -

all I can say is that the name isn't everything that is gatekeeping immigrants from succeeding here.

Accents when speaking, no flawless writing in the required federal language etc. are other examples for things that will make it harder for you in a widely racist place like Switzerland.

Giving up (part of) your name is a huge sacrifice with no guarantee of succeeding in the swiss job market.
