Marek Kurka, who worked as a hotel night manager in London and has spent most of his working life in the industry, was last seen on 2 July 2014 when he travelled from his home in Thornton Heath to Dover.
The 38-year-old was last seen in the St Margaret's Cliffe area on the same day and friends and family are becoming increasingly worried about him.
Police at Croydon's Missing Persons Unit are appealing for anyone in the industry who may have information on Kurka's whereabouts to get in touch.
