Manchester United, West Ham, Celtic, AC Milan and Borussia Dortmund have all been linked with the out of contract midfielder.
Hyndman, 20, could still perform a U-turn and sign an extension at Craven Cottage but a decision is imminent.
"I’m sure it will be decided very soon," he said.
"I’d say within the next month or so it should be all finished."
Hyndman has been frustrated by his lack of action at Fulham since making his debut in 2014.
An offer of regular first-team football could seal the deal but the USA international has plenty of different proposals on the table.
"Yeah, that’s another big thing," Hyndman told GotSoccer.
"There’s different sorts of clubs, different places, different leagues, there are different paths you can take.
"You take a bigger club and possibly not play as much, maybe go on loan or you can settle for a good solid club, maybe not fighting for the same things but you’ll get more chances along the way."
He added: "I feel like I need to make the best decision for me, personally and that’s going to take a little bit of time.
"I’ll take this time, discuss it with my family, people around me that really help me make these decisions and we’ll see."
