US: While many US Consulates are processing emergency visa cases only, the Department of State has announced that routine visa services resumption will occur on a post-by-post basis. With specific exceptions, foreign nationals who have traveled to the European Schengen area, the United Kingdom, the Republic of Ireland, Iran, China, excluding the Special Administrative Regions of Hong Kong and Macau, Brazil, and South Africa in the last 14 days are not allowed to enter the US. For a full list of exceptions, please refer to the travel restriction page of the CDC (Centers for Disease Control) website. All air passengers coming to the United States, including transit passengers, are required to have a negative COVID-19 test result or documentation of recovery from COVID-19, 1-3 days before boarding a flight to the United States.
UK: UK Visa Application Centers (VACs) have resumed services where local restrictions allow. If your VAC remains closed due to COVID-19 restrictions, you can apply online and select a VAC in any country worldwide. This is subject to the country’s entry requirements, your application and biometrics. For transit passengers, a negative COVID-19 test result within 72 hours of travel is required. If you have travelled to any of the UK’s designated Red list countries in the last 14 days prior to your travel, you are not allowed to travel or transit through the UK. Also, your application decision may be delayed if you’re applying from a country where travel to the UK is suspended. Please find here more information on UK visas.
Canada: Transit is possible if you arrive and depart from the same Canadian airport within 24 hours. Read here limitations on select airports and travel times. Please check Government of Canada travel guidance for more information.
