How long can a GC holder be outside the US?

[steffi]

So what is currently the recommended guidance for how long a greencard holder should be outside the US on a single trip? Is it 3 or 6 months?

12 months (you dont have to file anything if your stay is less than 12 months). If your stay is for more than 12 months and less than 24 months, you need to file I-131 (Re-entry permit) to enter the US.
