Leaving the US after I-485 got approved

[sk4f]

I got the I-485 approved (through national interest) but I intend to leave the US for family reasons. If I stay in the US another 6 months , leave and come back once a year can I maintain my Green card?
Thanks a lot

You cannot retain permanent residency simply by visiting once a year.
