How do China people earn money by working in Switzerland?

Due to Switzerland's wealth, Switzerland has not joined the visa countries of the European Union and has not used the euro. I heard that I was afraid that joining would affect their quality of life. Strict management of immigrants and strict standards for migrant workers. As a student at ordinary times, it is forbidden to work. Generally speaking, many students in China will choose Chinese restaurants or something, and have classes in the evening or afternoon about twice a week. However, those are basically illegal. Not only the workload is heavy, but also the income is not much. Generally around 30-40 yuan/time, but basically not less than half a day at a time. The monthly salary of a full-time employee may be between 65,438+0,500-65,438+0,800 Swiss francs, but accommodation is included. If you want to find a formal part-time job, it's really difficult. Because of the Swiss legal consciousness, when you look for a job, they will tell you clearly that they don't accept migrant workers like us international students, which is illegal.
