It has been weeks since she applied. Is this normal?
Yes verification can take few weeks and this is normal. If you have submitted every required documents than your wife might get her account verified there.
To fasten the verification process you can submit a support ticket.
But when I tried to verify my debit card by submitting selfie proof and photograph of card, I got reply emails within 30 minutes from submission time. I guess we must submit with them on European time zone and must be on week days. Anytime other than that, I guess may lead to delay than usual processing.
But one thing I need to mention here, my verification got rejected due to name mismatch. Does it mean approving takes time and rejections may occur in minutes ?
