From the New York Times:
After the visas of most visiting journalists expire [including, today, NPR’s correspondent and the Times’s Bill Keller], some will be able to remain. The BBC’s permanent correspondent in Tehran, Jon Leyne, recently had his residency extended by the government…Liz Cox Barrett is a writer at CJR.
NBC and The New York Times, among other outlets, also employ Iranian residents.
Similarly, The Associated Press has a large year-round presence in Tehran, including a number of Iranians. While visas for three of the wire service’s journalists are expiring, the operation will still have local employees in the capital city.
