In response to significant worldwide challenges related to the COVID-19 pandemic, the Department of State has temporarily suspended routine visa services at all U.S. Embassies and Consulates. Embassies and consulates have canceled all routine immigrant and nonimmigrant visa appointments as of March 20, 2020 but will continue to provide emergency and mission-critical visa services as resources and local conditions allow. We will resume routine visa services as soon as possible but are unable to provide a specific date at this time.
Please see these notices, posted at the link below, which contain detailed information about the current status of both non-immigrant and immigrant visa services worldwide and visa restrictions related to the COVID-19 global pandemic: https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/covid-19-travel-restrictions-and-exceptions.html
