What changes will national immigration policies bring to the country?

Speaking of immigration, I think literally, it should be to live in another place, but it has a deeper meaning. To some extent, it has changed people's nationality and re-created an identity for mankind.

For example, if we immigrate, we are not from China. In society, we don't enjoy the treatment that China citizens deserve. Now with the progress of the times, great changes have taken place in the immigration policies of various countries, and immigration will not be as difficult as we thought. Now more and more ordinary people will emigrate overseas, or many foreigners will emigrate to China. And what changes will this policy bring to our country?

I think everything has two sides. For example, emigrating to an exporting country may lead to a brain drain. Because people who immigrate now basically have good living conditions, if they apply for foreign nationality, their future income will not contribute to his country, and his potential customers will also be lost abroad. As a receiving country of immigrants, this country is undoubtedly very beneficial. Such excellent talents belong to that country, but there are policies in the world and countermeasures in the world. Many countries are trying to avoid brain drain, so immigration-related policies are not easy!

Immigration will also bring many benefits to our society, because immigrants will accept foreigners from that country, which will greatly promote cultural exchanges between the two countries. For example, they will bring foreign technology into China, which will also let people all over the world know more about their local customs. Also let the whole world know their own country, so this has advantages and disadvantages!
