Time limit to stamp passport after I-485 approval?

[nc 485]

Is there a time limit within which you need to stamp the passport after you get the I-485 approval? Does anyone know what this is? I know people rush to get it stamped right away, but I was just wondering, what if the person is outside the country for a few months.

No Title

During passport stamping, they take fingerprint of only
one finger, that goes into your plastic card. There\'s also
probably a I-89 that needs to be completed. I would
think your plastic card delivery will be delayed if you
delay going for pp stamping. Just my thoughts.
