Having a green card means he is here legally. Period.
You posted the article, so of course you know it’s the Washington Post.
Two independent sources are needed to find the truth about the Green Card.
Not going to argue with that because you are absolutely correct!
With that being said, Green Cards expire either annually or every five years, not sure which, and if not renewed, you are now in this country illegally!
This dumbass had every opportunity to continue to renew his card but chose not to. So after 40 years, he was finally busted. I have no sympathy for this guy........
FWIW, my two step-sisters were green card holders for decades until they became naturalized. One of them is married to a Honduran who was here legally for decades until he became naturalized. The other one chooses to remain a Canadian citizen even tho she is married to an American and has to renew her card according to regulations.
A green card still lets you be evicted for any offense.
Some open border liberals here on FR apparently don't understand Green Cards. You are required to obey all laws of the United States, the States, and local jurisdictions. (Pop quiz - what color are Green Cards?)
