Foreign travel advice
There is a general threat from terrorism. Attacks could be indiscriminate, including in places visited by foreigners. You should monitor media reports and remain vigilant at all times.
Individuals may be inspired to target public events or places, as demonstrated by attacks in New York, New Jersey and Minnesota over the weekend of 17-18 September 2016, Orlando on 12 June 2016 and San Bernardino on 4 December 2015, among others. Attacks could take place with little or no notice.
There is considered to be a heightened threat of terrorist attack globally against UK interests and British nationals, from groups or individuals motivated by the conflict in Iraq and Syria. You should be vigilant at this time.
The US Department of Homeland Security (DHS) provides public information about credible threats. Expect an increased presence of law enforcement and tight security at public places and events. This may include a heavy police presence, additional restrictions and searches on bags, and the use of screening technologies. For all current alerts within the United States and its territories, visit the DHS website.
