Aide to top Iranian nuclear negotiator pops up in Washington???

The Bush administration yesterday was at a loss to explain the rare presence in Washington of an Iranian government official who slipped into the United States under mysterious circumstances, apparently to attend a scholarly conference.

The State Department said that Mohammad Nahavandian, an economics and technology aide to Iran's top nuclear negotiator, Ali Larijani, "is not here for meetings with U.S. government officials."
[...]
State Department spokesman Sean McCormack could not explain how Mr. Nahavandian entered the country, saying only, "We have no record of issuing a visa to a person with this name."
[...]
Most officials yesterday were working on the assumption that Mr. Nahavandian has a green card that was obtained years ago, possibly when he was a student here, as sources in Iran were quoted as saying by wire reports.
