Re-entry Permit

[immihelp]

Can you tell me how long one has to stay in the USA to maintain a Resident Visa/green card? I have a re-entry permit that allows me to stay outside the US for two years. But my question is when I use it to go back, how long do I have to stay?

Thank you for your attention
