The Austrian government created Austrian Holocaust Memorial Service in 1991 to recognize Austria’s part of the collective responsibility for the Holocaust. Since then about 150 volunteers, mostly in their 20s, have worked in numerous countries in lieu of military service. Volunteers under this Austrian program have worked in the United States at the U.S. Holocaust Museum and the Simon Wiesenthal Center. Since Sept. 11, however, immigration authorities have raised repeated roadblocks in seeking visas for these volunteers.
