When director Abel Ferrara received a letter from IFC Films, the US distributor, telling the filmmaker to deliver an R-rated version so that it could match the version to be released on Showtime during its pay TV window, the director was disgusted and refused to back down telling THR "Welcome to New York is not being distributed in the U.S. because of this company, IFC, which I'm totally disgusted with." He stated "They knew from day one when they bought this film that they had the final version and that it wasn't going to be changed."

The $60,000-a-month three-story house that Simone (Jacqueline Bisset) rents for Mr. Devereaux's (Gérard Depardieu) stay while under house arrest, was the actual house that Dominique Strauss-Kahn's wife, Anne Sinclair, rented in 2011. It is located in Tribeca, New York.

When Gerard Depardieux's character is arrested, transported to jail and calls his wife in France he never asks why he has been arrested.
