After a renovation the consulate moved into the house in 1951 . The Consulate General is commonly called '' das Weiße Haus an der Alster '' ( the White House on the Alster ) in Hamburg . Since threats against American embassies , 9/11 , and a direct threat against the consulate in Hamburg , the security of the US Consulate General in Hamburg was often strengthened . On 1 April 2009 , the '' Hamburger Morgenpost '' used the consulate for an April Fools ' Day news , that because of security reasons the consulate will move to a WW II shelter at Heiligengeistfeld .

The Consulate is known for placing a large Christmas tree every year on the balcony over the entrance
