The former Celtic star has targeted a place in Roy Hogson's Brazil-bound side after moving to the Canaries in the summer.
Hooper had always cited possible international recognition as a key reason for the switch.He has been limited to four appearances and two goals for Norwich, but Hughton has confidence in the former Parkhead favourite.
He said: "They have a season of opportunity to force their way into the reckoning. It's a good opportunity for everybody."
"Gary's a good player. Unfortunately for us he got injured the week before the season started. But he's now back fit. It's Hodgson's responsibility to look at as many players as he can because you never know."
Meanwhile, Southampton boss Mauricio Pochettino insists Artur Boruc is not injured, despite claims to the contrary from the Poland national team.
The 33-year-old former Celtic keeper was left out of Tuesday's 2-0 World Cup qualifying defeat against England at Wembley.
Poland blamed his omission on a hamstring injury picked up against Ukraine.
Pochettino, though, says there is no problem with Boruc and expects him to be fit for tomorrow's trip to Manchester United.
"Artur is okay," the Saints boss said. "The news that has come out regarding his fitness is not true."
