Fer - signed by Norwich from FC Twente - intends to make the most of the opportunity as Holland prepare for their last two World Cup qualifiers against Hungary and Turkey, already safely through to Brazil as runaway winners of Group D.
Speaking to Dutch newspaper Algemeen Dagblad, Fer said: "It is far too early to talk about the World Cup, but playing in Brazil against the best players of the world is a once-in-a-lifetime chance.
"I will do everything to be part of that, but I can only do it in one way - give everything at Norwich and take all chances I get for the Oranje with both hands."
Fer, whose last senior call-up came as a substitute against Turkey in September 2009, continued: "It is really fantastic that I am here again.
"The first months at Norwich City gave me a good feeling, and the experience here in England is fantastic. Fortunately I could adapt quickly. I now also want to show that I have developed myself with Holland."
Fer produced an impressive display in Norwich's 3-1 defeat by Chelsea on Sunday at Carrow Road, in a match where the home side fought back in the second half only to be undone on the break as the Blues struck twice in the final five minutes.
Norwich's club-record signing Ricky van Wolfswinkel may not have been on the scoresheet, but worked hard as the lone striker, and it was his knockdown which set up Anthony Pilkington for the equaliser.
Van Wolfswinkel - who like Fer has been in and around the Dutch set-up - has yet to add a killer touch in front of goal, with his debut strike against Everton on the opening day his only scoring contribution since an £8.5million summer move from Sporting Lisbon.
