I think from memory its 21 days....
BUT, if you send the item, the buyer receives it and leaves feedback, you can call paypal and request to have the funds cleared straight away.
I have done it this way on a $1200 item and they cleared the payment straight after i called them....
The more you sell internationally, the quicker funds will be available....
I think they require 20 or more sales before they will clear funds directly after a payment has been made......
Hope that makes sense.
