American immigrants: the difference between green cards and American citizens

Hello, immigrating to the United States means becoming a permanent resident of the United States. A green card in the United States is proof of permanent residence in the United States. Having a green card means having permanent residency, that is, foreigners who can stay in the United States for a long time. "

If a permanent resident of the United States is sworn in as an American citizen through certain procedures, he is no longer a foreigner but an American. The differences between American citizens and American permanent residents (green card holders) are as follows:

1. American citizens can apply for relatives to immigrate to the United States.

2. Working in the federal government.

3, engaged in some special industries that only American citizens can do (such as military industry).

4. Citizenship cannot be revoked for almost a lifetime (the green card is likely to be revoked after the holder leaves the United States for a long time).

5. Elected and elected representatives of public opinion (members).

6. Serving in wartime and being protected by the United States overseas (American permanent residents are occasionally protected by the United States overseas, but it is not common and the intensity is small).

The suggestion was adopted. Thank you! Our skilled immigrants in Canada are RMB 300,000, and there is no charge for failure! !
