Traveling abroad? Consider these four basic questions.
Where are you going? Country sanctions and restrictions
In general, travel to most countries is not a problem with the exception of Cuba. In almost all cases, travel to Cuba requires a license from the U.S. Treasury Department. Research or other activities may be restricted in comprehensively sanctioned countries (i.e., Cuba, Iran, Syria, Sudan, and North Korea). The U.S. Treasury Office of Foreign Assets Control maintains the sanction regulations, which are unique to each country.
