1, the problem of related employment. Different labor contract subjects are actually related, mainly involving the economic compensation when you terminate the labor relationship with your current company. If there is no economic compensation, the working years can be extended to the next related entity, then assuming that the new entity has worked for you for one month or less after signing the contract with you, in principle, you can still claim all the working years (n) as the calculation base of economic compensation or compensation;

2. About signing the resignation application. Although this is the arrangement of the company in theory, it is mainly based on evidence when labor disputes occur. If the enterprise claims that you resigned by yourself, there will be no financial compensation, so pay attention to the possibility of being swept out of the house once you sign it, so you can reduce the risk by canceling the old contract and signing a new one at the same time.

3. The problem of visa refusal. The job adjustment you are worried about depends on the nature of your job. For example, if you are a salesman, the scope may be very wide, and if you are a shift worker, the scope is relatively narrow. It also depends on the provisions of your labor contract on the workplace. For example, if you are in a city, it may be tens of kilometers from west to east and from south to north, and it takes three hours to commute. This depends on some original cases decided by the local court, just like Shenzhen. As long as it is stipulated by Shenzhen, it is original. But the whole still depends on rationality.

4. The specific cases are actually different. I suggest you consult a professional lawyer to better protect your rights and interests. You can learn more about the labor law by following my official WeChat account "Eyes on the World".
