US embassies worldwide have suspended issuing visas due to operating failures.
“The U.S. Department of State is currently experiencing technical problems with its visa system, which are affecting global operations. This issue is worldwide and is not specific to any particular country or visa category,” says the website of the U.S. Embassy in Moscow.
“We recognize and deeply regret the inconvenience to travelers. We regret that we are currently unable to predict how long the delay will be,” the embassy said.
