Hi,
Its said that, it takes 3-4 working days only for visa. But for me, it took 8-10 days. ( 2 weeks before )

Once its approved, the status " Under processing " will get changed to " Ready to Print " in which case your PRO has to go to immigration, pay the money and then print it from there.

There is no other option to check the status. Just kee trying.

Regards
