Iran and the US cut diplomatic ties in 1980, and the players are expected to use their time in Türkiye to complete the necessary procedures for obtaining visas.
“No visas have been issued yet,” Mehdi Taj, the Iranian football federation head, told Iranian media on Thursday.
Taj said players were expected to undergo fingerprinting in Türkiye as part of the visa process, but wished to avoid a trip of more than 450 kilometres from Antalya to Ankara.
Taj is expected to hold talks with FIFA president Gianni Infantino as Tehran seeks assurances for its squad amid tensions increased by the ongoing war.
When the squad reaches the US, Iran will set up their base camp in Tucson, Arizona.
They are due to kick off their World Cup campaign against New Zealand in Los Angeles on 15 June, before facing Belgium in the same city and then Egypt in Seattle, in Group G.
