Switzerland issues work-related residence permits primarily to individuals with a confirmed offer of employment from a Swiss employer. The employment of non-EU and non-EFTA nationals is generally subject to annual quotas and labour market conditions established under Swiss immigration legislation. Employers normally initiate the application process and may need to demonstrate that recruitment efforts within Switzerland and the EU labour market were unsuccessful before employing certain third-country nationals. Residence permits are usually linked to the approved employment and may be renewable depending on the circumstances.
