Ethan Schilte-Brown says it would be "quite a jump" if he was to go from lower-league loan deals to the World Cup with Canada, but insists it is still his "dream".
The defender has featured for Canada's Under-20s and is hopeful he can earn a call-up for this summer's finals.
Schilte-Brown, 20, joined Killie's academy from the youth system of MLS side Orlando City in 2023 and had temporary spells with Canada's Halifax Wanderers, Cumnock, Albion Rovers and Dumbarton before impressing at Rugby Park this season.
Co-hosts Canada will face Iceland and Tunisia in a pair of international friendlies in late March as part of their World Cup preparations.
Prior to the Premiership game at Falkirk on Saturday, Schilte-Brown said: "My main focus is here and just trying to perform well for Killie, but if that's a by-product of what happens here then brilliant.
"That's the dream and it's never far from my thoughts but obviously my full focus is here right now.
"I think the gaffer spoke to them [Canada management team] but again I'm just focused here and I'm not going to read into anything until it's real or until it happens.
"That would be quite a jump [from loan deals]. I try and grow from every situation I am in. I learned a lot from Cumnock, Rovers and Dumbarton. It was really beneficial.
"As a young player, you need to play games. It doesn't do you any good just training all the time and no matter what level it is, there's a massive difference between playing with men and playing youth football, especially the physical side of it.
"You need to learn that if you're going to grow in the game and continue on.
"Playing first-team football is what everyone wants. That's where it's going to prepare you the most so I think it's prepared me.
"If I get called up, it's obviously an honour to get my first call-up, but I think with the World Cup in mind, you want to push on and prove to that manager that you're ready for that next step."
Killie are eight points ahead of bottom side Livingston and two behind St Mirren having played a game more than the Paisley side, but Schilte-Brown remains confident of retaining top-flight status.
He said: "I think there's every chance for us to get the safety. I think we will do it.
"The games that we have coming up are massive for us, especially the game this weekend with a sold-out away end, so just looking forward to it."
