Mattero Carrera, an immigration expert, has said that the easiest way for the Duke to sort his visa, would be by classification as a British diplomat, given his royal and financial assets. Meghan and Harry recently moved to California from Canada where they have been living for the past few months.
Mr Carrera told the Telegraph Harry would most likely be entering the US on an A1 visa.
He said: “With this he would have been able to enter the US and then adjust his status to a green card.”
