The money has to do with the transfer of striker John Antwi to the the Egyptian club. Having defaulted in initial payment, Ismaily were reported to Fifa.
The club's failure to honour their obligation the second time, under the supervision of the Egyptian FA as directed by the world football governing body, appears to be calling for dire consequences.
"World Football Governing body FIFA have issued a caution to Egypt that they could be dragged back home with just a day to their 2018 World Cup game against Uruguay," Dreams announced via their official website.
"This comes as a result of the Egyptian FA failing to let Ismaily comply with an order to pay an amount they owe Ghana Premier League side Dreams FC which dates back to 2012 following the transfer of John Antwi.
"FIFA gave Ismaily until 23 May, 2018 to pay all monies owed Dreams FC and they also copied the Egyptian FA to see to it that the Mango Boys have cleared the debt.
"Agonizingly, all this has been flouted by Ismaily and the Egyptian FA and FIFA have made it clear that the next option is to send the Pharaoahs back home from the Mundial in Russia until the debt is settled.
"Antwi signed for Ismaily in 2012 for an amount in excess of $150,000 and won the Egyptian top-flight goal-king award in the 2014/15 campaign."
