Да не се бърка "permаnent resident" с "resident of the US" .

Второто означава просто човек живеещ в пределите на САЩ. Справка:

........
(b) What "resident of the United States" means. We use the term resident of the United States to mean a person who has established an actual dwelling place within the geographical limits of the United States with the intent to continue to live in the United States.

(c) What "United States" means. We use the term United States in this section to mean the 50 States, the District of Columbia, and the Northern Mariana Islands.

Примерно изискването за кандидатите за президент е да са родени в САЩ и да са били RESIDENT за последните 14 години.
