I am a lawful permanent resident (i.e. green card holder). My SSN card doesn't have any endorsement; it appears exactly the same as a US Citizen's card. When I was on a nonimmigrant visa, it did have the endorsement "VALID FOR WORK ONLY WITH DHS AUTHORIZATION" as I needed an Employment Authorization Card to work. (They granted my green card before they approved the EAC though.)
