Do I have to live in an immigration prison to immigrate to Switzerland?

First of all, a green card is not a nationality, it is also called permanent residency, permanent visa, PR, etc. It just proves that you can stay in this country permanently without a visa. The green card has nothing to do with nationality.

In other words, if you get a green card, you are still a citizen of China, and you can go back to China or stay in Switzerland without a visa.

A green card is definitely a big advantage for your future job.

If your company has business dealings with Swiss companies in the future and needs to send people on business trips or long-term assignments, you will have great advantages if you have a green card. Because you don't need a visa no matter how long you stay in Switzerland, and it proves that your language and living habits can be integrated into Switzerland.

There is nothing to pay attention to in the green card. Personally, I think there are gains and losses.

With a green card, you can stay in China and Switzerland indefinitely without restrictions. You can also get local benefits.

However, the green card has the problem of "immigration supervision" (commonly known as not a real prison, don't worry).

Australia's "immigration supervisor" is: stay in Australia for a few months every year for the first five years (I forgot specifically), and then return to Australia regularly.

The situation of "immigration supervision" is different in every country, so you'd better understand it clearly.
