My wife's FOID will expire this November and we are uncertain if she should go ahead and process ($$$) a change of address now or it is an option to change it during the renewal process as soon as the renewal option is available on her dashboard. We know the card is still valid with our old address, but didn't know if this would throw a wrench into the renewal with the new system if we waited to make the change when the renewal option is available. It wasn't until recently that we came across the 21 day rule after changing residences a few years ago. She is not CCL'd or making any purchases, so conformity for an FFL is not a concern.
