for the SASE no you can't put UK 1st class stamps on the SASE, because it would be coming from America, and they can't use UK stamps, it has to be American stamps.

Or you can include IRCs (International Reply Coupons) which you can buy at your post office (usually the large branches). These are included with your addressed envelope & the recipient can exchange them for stamps of their nationality.
