West Ham will face either Shakhtyor Soligorsk of Belarus or Slovenian side Domzale in the third round of Europa League qualifying.
The first leg is currently set to take place at the Olympic Stadium on July 28, with the second leg following a week later on August 4.
However, the Hammers have appealed to UEFA over switching the home and away legs around as the Olympic Stadium will be used for the London Anniversary Games on the weekend of July 22.
It usually takes seven days to convert the stadium from athletics mode to football mode and this therefore causes an issue for West Ham, who have held positive talks with both clubs over a switch.
"In order to give Stadium owners E20 Stadium LLP as much time as possible to prepare the arena for its first taste of European football, the club have today made official representation to request that the fixture be reversed," a West Ham statement read.
"If successful, Shakhtyor Soligorsk of Belarus or NK Domzale of Slovenia will visit Queen Elizabeth Olympic Park for the return leg on Thursday 4 August.
"Following post-draw discussions, both clubs have agreed to West Ham's request in principle and a final decision is expected to be ratified by UEFA in due course.
"Owing to the date of the Europa League fixture, the club has had to agree to work to a capacity of 54,000 for the Hammers' first two fixtures at London Stadium.
"And, given the proximity of the Anniversary Games to those opening two West Ham games, Stadium owners E20 Stadium PLP are doing their utmost to prepare the venue fully into football mode accordingly."
