As of June 15, 2015 the Department of State has been experiencing severe issues with its computer system, which is preventing them from issues visas and passports. According to the DOS:
This is a global issue, and we are working around the clock to fix it. More than 100 computer experts from both the private and public sectors across the United States are working on this problem 24/7. That said, we do not expect the system will be online before next week. The problems stem from a hardware failure in a State Department facility in the United States on June 9. That failure is preventing the Department from processing and transmitting biometric data checks at visa-issuing embassies and consulates. We cannot bypass the legal requirements to screen visa applicants before we issue visas for travel. Each visa decision is a national security decision, and we take our obligation to protect the United States seriously.
