The 26-year-old has only started one Premier League game since joining Newcatle in a £6million deal from Ajax.
De Jong is ready to stay at St James’ Park until 2020 and then head off to the MLS.
“I can certainly stay here for five years, Tim Krul has been here for 10 years – but it does depend on many factors,” he said.
“I am adventurous even though I stayed with Ajax for seven years. I would certainly look at the end of my career towards New York or Los Angeles. I’ve been a few times to the US. I travel a lot anyway.”
