No. U.S. citizens are born in the United States, become citizens through their U.S. citizen parents, or through naturalization. Citizens have certain unique benefits, such as the ability to reside outside the United States indefinitely and the ability to vote in U.S. elections. Also, assuming that there was no fraud in the immigration process up to and through naturalization, citizenship is very hard to lose.
Lawful permanent residents, on the other hand, have a less secure status in the United States than U.S. citizens. These residents are given what’s known as a “green card,” which allows them to live and work in the U.S. and petition for close family members to also receive permanent residence in the U.S. This status is not truly permanent, as it can be lost. Commission of certain crimes can result in removal (deportation) proceedings against permanent residents. Further, permanent residents can lose their status through excessive absences abroad that are indicative of an intention to abandon residence in the United States. Permanent residents must also continue to update the U.S. government of their addresses within 10 days of moving and renew their green cards prior to expiration.
