What do you usually mean by immigration? Do you mean getting a green card or becoming a citizen of another country? Seek an explanation

People from one country apply to live and work in another country for a long time, get approval from that country, and then go abroad. This process is called immigration. Immigrants have the legal right to live and work permanently in the country, that is, the so-called permanent residency, but they do not immediately have foreign nationality. We usually refer to "overseas Chinese", that is, China people who live abroad but still have China nationality and hold China passports.

Second, the green card

After a foreign country has permanent residency, usually this country will issue an identity certificate, similar to our domestic identity card, to prove this person's permanent residency. This kind of certificate is commonly known as "green card" in the United States, but it has different names in other countries, such as "maple leaf card" in Canada and "login card" in Japan, but the meaning is the same.

4. The difference between naturalization and immigration is that naturalization has five rights and obligations, which immigrants do not enjoy and perform. 1 Voting right 2 Elected 3 Elected jury member 4 Served in military service 5 Served in the government. Moreover, passports are different. Immigrants get China and passports. If you immigrate to Canada or some developed countries, you don't need a visa to go to Europe, America, Canada and Australia after naturalization.
