Internacional president Giovanni Luigi has said that Oscar's move to Chelsea is on the verge of completion.
It was announced on Sunday that a fee in the region of £25m had been agreed for the 20-year-old.
Luigi has also revealed that the Blues will pay the amount owed to Sao Paulo, where Oscar played until his move to Internacional in 2010.
"The situation is very advanced, but not finalised yet," Luigi told Terra. "Oscar has to get his work permit. He needs to have a certain amount of caps to play in England, but I don't believe that will be a problem.
"I won't confirm the value, but I can guarantee it wasn't in pounds. No cross-border negotiation is made in pounds - it's either Euros or dollars.
"I have also reached an agreement with Sao Paulo over their part. It's Chelsea that will pay that, not Internacional."
Oscar has made six appearances for Brazil.
