The United States and Cuba had severed diplomatic ties in 1961 during the Cold War era. Relations were restored on 20th July 2015. US embassy in Cuba is in the Cuban capital of Havana and the Cuban embassy is in Washington, D.C. The US still maintains its economic, financial and commercial embargo making it unlawful for American firms to engage in trade with Cuba. Even though the then US President Barack Obama had stated his intentions of ending the embargo, US law makes it mandatory to have the approval of the Congress to terminate the embargo.
