The former Socceroos boss is calling for football's global governing body to come up with an alternative plan for Iraq's crunch World Cup play-off scheduled to take place later this month.
The Lions of Mesopotamia are set to face a one-off match with the winner of a play-off between Suriname and Bolivia in Monterrey, Mexico, on March 31, with the FIFA window due to start on March 23.
That match with either Suriname or Bolivia will decide if football-mad Iraq qualifies for its first global tournament since 1986.
But preparation for Iraq's match has been plunged into turmoil by the widening conflict in the region.
Iraqi airspace is not due to re-open until April 1, the day after Iraq's scheduled fixture with the winner of the Suriname-Bolivia clash.
Arnold, speaking to AAP from the UAE as he received an emergency alert on his phone, has a simple request for FIFA: "Please help us with this game because right now we are struggling to get our players out of the country of Iraq."
Close to 60 per cent of Arnold's first-choice squad is drawn from the domestic Iraqi league but those players and many of his backroom staff, including interpreter and former Sydney FC winger Ali Abbas, remain unable to fly out of Iraq.
A pre-match camp in Houston has already been postponed, with visa and travel uncertainty placing further strain on Arnold's plans.
"In my opinion, if FIFA were to delay the game it gives us time to prepare properly," Arnold told AAP.
"Let Bolivia play Suriname this month and then a week before the World Cup, we play the winner in the US - the winner of that game stays on and the loser goes home.
"In my opinion, it also gives FIFA more time to decide what Iran is going to do.
"If Iran withdraws, we go into the World Cup and it gives the UAE, who we beat in qualifying, the chance to prepare for either Bolivia or Suriname.
"Our federation's president Adnan Dirjal is working round the clock trying to plan and prepare to make everyone in Iraq's dream come true so we need this decision made quickly."
If FIFA can't help with Arnold's request, the 62-year-old fears for how his players and staff will get out of Iraq at such short notice.
Some of Iraq's domestic football matches have also been impacted by missile attacks in Erbil, where there is a US airbase.
Arnold said there was little hope of fielding a competitive team solely drawn from players based outside of Iraq.
"It wouldn't be our best team and we need our best team available for the country's biggest game in 40 years," he said.
Arnold is desperate to help Iraq to their first World Cup in four decades.
The Australian took the Socceroos to the 2022 tournament and made a historical charge to the round of 16 where they lost to eventual winners Argentina.
"The Iraqi people are so passionate about the game of football that it is insane," Arnold added.
"The fact that they haven't qualified for 40 years is probably the main reason I took this job.
"But at this stage with the airport being shut down we are working hard to try and find another alternative."
