• Cuban National and Resident of Cuba
• Educational activities and people-to-people exchanges
• Travel related to certain authorized export transactions
• Family Visits
• Official Business of the US government, foreign governments and certain intergovernmental organizations
• Humanitarian projects
• Exportation, importation or transmission of information or informational materials

• Religious activities
• Support for the Cuban people
