The AFC South side will play one of their home games at Wembley Stadium for the next four years, but NFL commissioner Roger Goodell recently suggested that the Jags could double that commitment.
"What we're focused on right now as a team is four games in London for the next four years," ESPN quotes Khan as saying.
"That's very important to us. I think everyone needs to understand playing games in London is very, very important for Jacksonville, it's very important to this franchise. We need fans, we need more corporate sponsors.
"Jacksonville is excellent in fan support, great facilities that we're going to have. We don't have enough corporate sponsors. London is the missing piece but right now, our focus is the next four years with one game."
The Jaguars will play the San Francisco 49ers at Wembley on October 27.
