If you are sure you haven't received the email even after 3-4 days better call them and confirm. Make sure you didn't miss it anywhere in your inbox. this isn't normalHello!
I sent ACS application online on March, 14th. On the same day I sent the hard copies by DHL and they are not there yet. On March 15th, the status changed to Awaiting Documents and there is a text:
"A Request for extra documents or information has been sent to your email address. Please check your email address for further details."
The problem is, I have not got any email from them. Is it normal?
