Cuban soil is not actually off-limits to Americans. But the Treasury Department forbids United States citizens to spend money there without authorization, effectively barring tourist travel. Even prepaid tours booked in another country are illegal without authorization. On paper, although not in practice, a violation can lead to a fine of up to $55,000. Theoretically, violators could also face criminal prosecution and a fine of up to $250,000 and 10 years in prison. http://query.nytimes.com/gst/fullpage.html?sec=travel&res=9D02EFDC113DF936A3575BC0A9679C8B63
Но обычно - "всего" 7500 баксов штрафу. Если не докажешь, что_не_тратил_там_денег. Действует презумпция виновности.
