If you live in the US, send a stamped and self-addressed envelope (8.5" x 4") with your request letter and a photo. You could also include a piece of cardboard to keep the photo from bending during shipping. There is a 3+ month wait for a response on average. If you live outside the US, add several International Reply Coupons (IRC) inside the envelope (not on it). The coupons will be used by the receiver to purchase American stamps. IRCs are only available at a post office.
