Zaina al Sabah bin Laden, 52, the former Jane Felixe-Browne, told GMTV Omar bin Laden, 26, applied for a visa in December and has not received any response. She says they intend to appeal to the European Court of Human Rights.
"We think 99 percent that it is going to be a refusal though there has been no official letter," she said in an interview from Paris.
The couple married last year after meeting at the Pyramids in Egypt. Zaina bin Laden, who is from Moulton, Cheshire, has been married and divorced several times.
She said they have already retained an immigration lawyer and been in touch with a member of the European Parliament.
Omar bin Laden says he left Afghanistan in 2000 and has not seen his father since. He is one of 19 children Osama bin Laden has fathered with four wives.
