Professionals provide help on immigration issues.

It depends on what kind of immigrants you are referring to, whether you simply get a green card in the United States or become an American citizen (similar in other countries, Australia, New Zealand, etc. )

First of all, no matter which country's green card you are holding or which country's citizens, you need to go to this country by yourself. You can't stay in China and get a visa from another country.

Then, analyze your needs. If it is a green card, it is actually a permanent resident visa. Every country has different time limits. Australia will give five years, and sign every five years 1 time. The United States is 10 year, and it is updated every 10 year. With this green card, you can have the right to enter the country indefinitely within the validity period. And can live. Do you have a passport or a China passport? You are still from China. You can return to China to live, but there is a time limit. Australia has to live in Australia for two years in five years, and there is no continuity, so you can sign a new five years after the expiration of the five years. The United States does not return to China for more than six months at a time. When you say abroad, you mean your visa country. That's right. If you come from another country, you are still a citizen of China and still need a visa.

If you apply for a nationality, it means that you have given up your China nationality and joined a foreign nationality. You have a foreign passport. Then you can only live in America or your country. You can go back to China, but instead, you need to go to the China Embassy to sign a visa to enter the country, otherwise you can't go back to China.

If you just want to travel, it is recommended to sign a tourist visa, which is convenient, inexpensive and not so worrying.
