Will there be any issue if I file for I485 couple of years after my PD is current.

I have an approved I140 and PD is current now. At present I am outside US and planning to find some employer after 1 year. Will there be any issues waiting for more than year to file for I485 ? Can USCIS repeal my visa number if I have not used it for more than a year ?

I appreciate your time for reading my post. Looking for advise !!!

Thanks
