There are not many days at the moment when we are not shipping somebodies personal effects overseas. Here you can see a 40ft container being loaded for the USA. Despite its tight policy on who can enter the country there are still plenty of UK residents who have the specialist skill sets that allow them to get the necessary visas to work in America.
Typically it takes two and a half days to pack up a home and then half a day to load the shipping container. With America being such a vast country it is rare to ship two consignments to the same place within the same month.
