Don't emigrate to live abroad.

It is ok to apply for a work visa, but you may be confused about the concept of immigration. Generally speaking, immigration is a green card. You are still a citizen of China, but you have the right of abode in that country. If you want to change your nationality, you should change it after the green card comes down. If you are willing to change, you will find it inconvenient to live abroad with a work visa all the time. For example, children who don't follow you to school are international students, and your medical expenses are not locals, although some countries have individual work visas.
