The team informed the Federation of International Lacrosse (FIL) and event organisers of the issue.

They are scheduled to play on the first day of competition tomorrow at Netanya Stadium as they look to improve on their bronze medal-winning performance at the last edition of the event in 2014. 

"The Federation of International Lacrosse is working to assist the Iroquois nationals and the Israel Organising Committee to resolve this issue," FIL President Sue Redfern said. 

"FIL would very much like to assure the presence of the Iroquois nationals at the 2018 FIL Men’s World Championship."

On behalf of the Organising Committee, David Lasday, chief operating officer of Israel Lacrosse, added: "The Organising Committee is working diligently to assist the Iroquois nationals to be able to board their flight to Israel for the Championship. 

"Their participation is very important to the success of the event."

The unique nature of the Iroquois nationals has led to challenges procedurally using Haudenosaunee passports for travel and entry into Israel. 

The Iroquois nationals are comprised of players from the Haudenosaunee, a federation of six indigenous nations, including the Mohawk, Oneida, Onondaga, Cayuga, Seneca and Tuscarora nations. 

The Host Committee for the event and FIL are working together with the Iroquois nationals to solve the current challenges and expect that the issues will be resolved in time to allow the team to be present for their opening game against the United States tomorrow.

"As information becomes available, we will release it accordingly," Redfern said.

"We’re very hopeful in working out details and accepting the arrival of the Iroquois nationals here in Israel."

Ansley Jemison, executive director of the Iroquois nationals, was reported as saying by the Canadian Broadcasting Corporation that travelling on their own passports is at the core of its programme.

"We're indigenous people,"he said.

"We have treaties with Canada, we have treaties with the United States and it's our right to be able to travel as indigenous people. 

"We want to be able to have that movement.

"We're just waiting on a letter as some sort of confirmation that the green light is there."

The 2018 Men’s Lacrosse World Championship is due to feature 46 national teams, more than ever before, in a 10-day event with all playing to a final placement.

Canada, winners of a third World Championship title in 2014 in Denver, are aiming to return to the top of the podium. 

The 12th edition of the event is divided into 15 pools, with the blue division featuring the top-six-placed teams from the 2014 World Championship, and the remaining 14 pools including three teams each. 

The blue division will see each team play five pool play games, with the top four teams advancing to the championship round and the top two receiving byes to the semi-finals.

Canada are likely to face tough competition, especially from the US, winner of nine gold medals and three silver medals.

Also competing in the blue division will be the Iroquois nation and Australia, striving to re-bound after a fourth-place finish in 2014. 

Australia has been a perennial powerhouse, having claimed medals in nine of the 11 last World Championships. 

England and Scotland round out the blue division.

Host nation Israel are due to start their red division campaign against Jamaica tomorrow at the Netanya Stadium. 

Israel, a member of the FIL for the last seven years and staging the World Championship for the first time, has increased participation for the sport through public appearances at schools and sporting events. 

Coming off a seventh-place finish in 2014, the country has been active in the last year with a strong preparation schedule against top countries and clubs.

Russia is making its second appearance at a World Championship.

Hong Kong and debutants Luxembourg are set to open the event tomorrow. 

Both teams will be competing in the Olive Division.

The majority of the competition is scheduled to be held at the Wingate National Sport Institution, Israel’s National Centre for Physical Education and Sport. 

The Netanya Stadium will host the Opening and Closing Ceremonies and gold-medal game on July 21.
