What are the chances of staying in Switzerland for development after studying in Switzerland?

It's unlikely. Switzerland is a non-immigrant country, and the conditions for wanting to stay and work here in the future are very harsh. If you want to be employed by a Swiss company, you must first obtain a work residence permit, and if an employer wants to apply for a work residence permit for a China person, he must have sufficient reasons to prove that the job position must come from this China person (the government stipulates that companies or enterprises must provide jobs for their own people first, followed by Europeans, and if no suitable person can be found, only people from other countries will be considered). /zd/lx
