The Glass Wall (1953)

Unable to provide the identity of the one witness of his assistance of Allied soldiers during World War II, Hungarian immigrant Vittorio Gassman jumps ship in New York Harbor to evade immigration officials. Knowing only the man’s first name and that he works in Times Square, Gassman has a day to find him or risk never being able to enter the country again. It’s a tight little chase film with Gassman searching the dark streets of New York finding allies and foes on every corner. There’s a neat climax at the new United Nations headquarters that includes a somewhat heavy handed soliloquy over the treatment of immigrants particularly as a step in spreading peace and freedom throughout the world.
