I assume that the problem with Paypal is going to be permanent. They should have at least send us a notification email for those who doesn't have an US bank account before implement this new regulation.
Anyway, I have tried sending out another email to Paypal asking for updates about the acceptance of payment without a US bank account again.
However, after reading the post by Weirdoux today, I've decided to get a VMI ATM card asap. The complete procedure can be found at HongKiat's blog.
Hopefully there will be no problem sending out fund via Paypal to complete the application. Anyone have any clue?
