Iran's football federation has said it will lodge a complaint at the ruling body FIFA over the tight arrival and departure procedures around their World Cup matches in the United States.
A statement said that the US-imposed restrictions imposed on its own team are incompatible with the principles of creating a level playing field for the participating teams.
Iran's team was only allowed to travel from their their Mexican base camp on the eve of their first match in Inglewood, California, where they drew 2-2 with New Zealand.
They said they have also not received permission to travel two days ahead of their next match on Sunday at the same venue against Belgium.
Some Iran delegation members have also been denied entry to the US altogether.
Team officials said that FIFA president Gianni Infantino visited the Iran team in the dressing room after the New Zealand match and offered to help them.
The US and Iran have been in a military conflict since February. A framework agreement aiming to end the hostilities was signed on Wednesday.
