People often talk about Green Cards, when they are discussing US Immigration and US citizenship, but not everybody is sure what they are and what the term really means.
In this article I hope to respond in language that is easy to understand to questions such as:
What are Green Cards?
Why they are called Green Cards?
What the term US Lawful Permanent Residency (LPR) means?
How people become Green Card holders?
Which agencies issued Green Cards before the United States Citizenship and Immigration Services (USCIS) came into existence?
Whether it is possible for a Green Card holder to lose their US Lawful Permanent Residency status?
What are the rules regarding Green Card holders carrying them on their person?
