I'm a verified BitStamp user since June 2013. USD wire withdrawals in the past without issue. I tried to do a USD withdrawal this month, and received the KYC questionnaire. I answered all the questions and provided high-res scans of the documents they requested. It's been about 2 days so far, no response to the support ticket.
It was about five hours for me back in January. The withdrawal was processed the next day.
