If you’re planning a trip abroad, you should either call the State Department’s travel advisory service or visit its website.
The department can tell you what Travel Warnings and Travel Alerts are issued for various destinations. Travel Warnings are issued when long-term, protracted conditions make a country dangerous or unstable. Travel Alerts are issued to disseminate information about short-term conditions that pose significant risks to the security of U.S. citizens.
The website tells you about passport and visa requirements and provides up-to-the-minute information on safety issues, including terrorist activity. It also makes recommendations about whether you should take valuables with you and warns about driving in rural areas in some countries.
