My spouse entered the U.S. on an H-1B visa stamp but the H-1B visa stamp in his passport has expired. He changed employers and have a new H-1B approval notice which authorizes him to work for my new employer. Although his H-1B visa stamp has expired, He has a valid I-94 and a valid passport. He is going to Canada for soft landing . Can He take advantage of the automatic revalidation rule?
