Documents needed to enter U.S. for greencard holder

[susien wirogo]

Hello,

I need to go out of the country for bussiness purpose and I am wondering if there is any other documents that I need to have (besides passport and the greencard) to enter U.S. ?

Thank you

You do not need any other documentation if you either have a I-551 stamp or the actual plastic card
