A federal court said US officials were obligated to give a Muslim scholar a chance to show he was no supporter of terrorism before barring him from the country.
Professor Tariq Ramadan had his visa revoked in 2004 while he was about to take a job at the University of Notre Dame in Indiana.
His applications for a new visa were denied on the grounds he had donated money to a charity that supported the Palestinian terror group Hamas.
The federal appeals court in Manhattan ruled today that it was legal for the government to refuse Ramadan, but said it had to give him the chance to prove he didn’t know his money would go to a terrorist group.
Ramadan will be allowed to reapply for the visa.
