How can I go abroad without social security?

Let me explain your present situation:

After emigration:

1. Stop paying social security. Surrender is in accordance with the process. Go to the social security bureau under the jurisdiction of Shanghai for surrender and withdraw part; If you return to China in the future, you can't participate in China social security because of your foreign nationality; The previous insurance record will also be cancelled and cannot be continuous;

2. If you don't pay for medical insurance, you will automatically stop, and you can't continue in the future.

The above is the whole process. Even if you return to China later, if your nationality is not China, you can no longer apply for insurance according to your current household registration.
