Can I immigrate to Switzerland after studying for a PhD?

1. It is stated that immigration needs to be approved by the federal, state and living town. They have lived in Switzerland for 12 years and can immigrate after meeting the federal naturalization conditions.

2. Meet the naturalization requirements of other immigrants: you can live in Switzerland by observing Swiss laws and mastering the official language. People who have not broken the law can adapt to life in Switzerland as long as they live in Switzerland for 12 years, so they can live in Switzerland if they meet the conditions.
