Itzcovitz appeals from so much of the opinion below as denied him relief against the Immigration and Naturalization Service; before argument, the government withdrew its cross-appeal from the order enjoining the Selective Service System from proceeding against Itzcovitz. Since the argument of the appeal the government has conceded the propriety of admitting Itzcovitz into the country, and the parties have informed us of his return.

The appeal is dismissed as moot.
