You can get them from workplaces, places you volunteered, or people that know you that can vouch for you for that period of time. Teachers, colleagues.
It is basically a statement written by them signed and dated. JJGLO I think posted a template. But, I have to look for it.

It doesnt' have to be two affidavits it can be one. Just as long as is from someone that has known you from that period of time.
