An Iranian friend of mine had been living in the U. S. for three years, working on his Ph. D. and also working for a company here. He left for Iran in December of 2008, hoping to return within one or two months. But the visa-issuing process has dragged out so long that he had to resign from his job, which makes getting a visa into the U. S. even harder. Whom can I express my frustration to, besides the Department of State?
