Clarke visited potential sites in the United States before settling on Charlotte and Fort Lauderdale as the two main bases for his squad this summer.
Scotland will play Haiti (14 June) and Morocco (19 June) in Massachusetts and finish Group C in Miami against Brazil (24 June).
“I always wanted to go to a World Cup with my country, so I’ve now done that,” said the former Chelsea and St Mirren defender, who won six Scotland caps.
Asked whether the ball was now in the SFA’s court, Clarke was happy to agree.
“Yes, I think it is,” he said. “I’ve had a very brief conversation with Ian [Maxwell, SFA chief executive] about what they want to do moving forward.
“But I think I’m waiting on the Scottish FA now coming to me and saying, ‘look, this is what we see as the future’ and if I’m part of that then we can have that discussion.”
And Clarke admits he’s shifted slightly in his own mind, having previously said his chances of staying were only 25 per cent. He says he’s now more “50-50” and is not phased by the fact nothing’s yet resolved.
“It’s been busy for everyone so I’m not surprised,” he added.
