The 27-year-old was part of the Honduras team that clinched a place at the 2014 finals in Brazil after a 2-2 draw in Jamaica in October.
Izaguirre's performances at the last World Cup in South Africa earned the left-back a move to Celtic, and he is keen to build on that experience.
Honduras only picked up one point on their debut appearance at the 2010 finals, but Izaguirre is hopeful that experience will lead to a better showing next summer.
"The most exciting thing about the World Cup is just qualifying for it as it made people all over Honduras so happy," Izaguirre said.
"It's still a new experience for us. When we went to South Africa we had no experience of playing in a big tournament and now we have that so hopefully we can have a good World Cup.
"We have been striving for this for four years since the last World Cup in South Africa, and we are all very happy in Honduras, whether it's the fans, our families or everyone in the country.
"It's very exciting and I have to thank God for this moment as going back to the World Cup is fantastic."
