The former Arsenal striker has been told he can leave the Nou Camp after showdown talks with club director Joan Oliver.
Henry’s departure is tipped to be finalised on Thursday when New Barca chief Sandro Rosell takes over from outgoing president Joan Laporta.
The club insisted on Tuesday that Henry had been told of his decision before he joined up with his national side for South Africa.
Oliver said: "It was agreed a few weeks ago. Now it is up to him to complete it. This will allow Barca to save money on his wages in the next financial year."
Henry joined the Catalans from Arsenal in 2007 but, despite winning the Champions League in 2009 and two La Liga titles, he has not been able to replicate the form he showed in London.
Henry, 32, is set to join Major League Soccer's New York Red Bulls after Spanish champions Barcelona said they had agreed to part mutually.
The Frenchman helped Barca to six major trophies in 2009, including the Champions League, but scored only four goals in the season that just ended.
He was reputedly one of the highest paid players in Pep Guardiola's squad and his departure will allow Barcelona to save money in the next financial year.
Reasons I want Henry to come to America:
He tells the best stories...
But he'll shut up so you can speak as well
He's going to wait all day for you if he has to.
Even if he can't see your eyebrows, he is there for you.
Titi, I'll pick you up at the airport in 5 min, ok?
I would love for his ping pong buddy to tag along to NY, but we will see.
p.s. This is my first post on here and it would be WONDERFUL if you posted your favorite pics/vids of Mr. Henry. Show him some love people!
