The U.S. Department of State warns U.S. citizens of the risks of travel to Eritrea and strongly recommends U.S. citizens not travel to the country since there is increasing possibility U.S. citizens will not receive the requisite exit permit from Eritrean authorities. This replaces the Travel Warning for Eritrea of November 18, 2013 to remind U.S. citizens of ongoing security concerns in Eritrea
The Eritrean government continues to restrict the travel of all foreign nationals. These restrictions require all visitors and residents, including U.S. diplomats (who must apply 10 days in advance) for permission to travel 25 kilometers outside Asmara's city limits. Permission is usually granted to areas such as Massawa and Keren, which are known tourist destinations; however, requests to areas near the borders and regions not frequently traveled by diplomats are typically turned down. As a result, the U.S. Embassy cannot guarantee its ability to provide consular assistance outside of Asmara.

Modern telecommunications options are limited in Eritrea and cannot be counted upon in an emergency. International cell phone service plans do not work on Eritrean networks. Local cellular phone service is tightly controlled by the Eritrean government and difficult to obtain. When available, international cell phone calls are extremely expensive and only available using pre-paid minutes. Internet cafés are widespread but often lack power. Internet service is limited and slow, and generally does not support Voice over Internet Protocol (VoIP) services such as Skype.
The U.S. Embassy in Asmara strongly urges U.S. citizens who travel to or remain in Eritrea despite this Travel Warning to enroll in the Smart Traveler Enrollment Program (STEP) so you can receive the most up-to-date security information. Please keep all of your information in STEP current. It is important when enrolling or updating information to include multiple phone numbers and email addresses to facilitate communication in the event of an emergency.
