Got GC six years, want to return to own country what forms to file?

Hi Folks,

I got my GC six plus years now. I do not want to apply for US Citizenship.
However, I want to return to my country for more than six months, say
two years.

What forms do I file to give me permission to stay outside USA? So that my
GC does not expire being out of US for six months or more.

Please oblige, thanks,

Regards,
Piya Love

Apply for a re-entry permit using form I-131.
