Ditto on what FSUZeta said. It depends on what office you'll be advising. If you're Recruitment or Member Development (or whatever you guys call them) advisor, then you'll probably have to put in the extra time to attend chapter/committee meetings.

I became an advisor only 2 years after going alum, even though AGD asks us to wait 4-5 years just so there isn't any conflict of interest you might have with girls who were in chapter at the time you were in it. Since you're at a different school now, it won't be a problem for you.

I was Campus Relations advisor, held two part time jobs and went to graduate school part time, and it wasn't that big of a problem for me because all I was required to do was attend monthly EC and random meetings here and there.

Congrats for wanting to be more involved with your org!
