Tariq Ramadan in the Chronicle of Higher Education:
In late September, I finally received a response to the question I had been asking the Bush administration for more than two years: Why was my work visa revoked in late July 2004, just days before I was to take up a position as a professor of Islamic studies and the Henry Luce chair of religion, conflict, and peace building at the University of Notre Dame? Initially neither I nor the university was told why; officials only made a vague reference to a provision of the U.S. Patriot Act that allows the government to exclude foreign citizens who have “endorsed or espoused terrorism.” Though the U.S. Department of Homeland Security eventually cleared me of all charges of links with terrorist groups, today it points to another reason to keep me out of the country: donations I made totaling approximately $900 to a Swiss Palestinian-support group that is now on the American blacklist. A letter I received from the American Embassy in Switzerland, where I hold citizenship, asserts that I “should reasonably have known” that the group had ties with Hamas.
What American officials do not say is that I myself had brought those donations to their attention, and that the organization in question continues to be officially recognized by the Swiss authorities (my donations were duly registered on my income-tax declaration). More important still is the fact that I contributed to the organization between 1998 and 2002, more than a year before it was blacklisted by the United States. It seems, according to American officials, that I “should reasonably have known” about the organization’s alleged activities before the Homeland Security Department itself knew!
