Eritrean passport Wikipedia
The Eritrean passport is issued to citizens of Eritrea for international travel. Citizens are not issued passports prior to completion of military service. Eritreans living abroad only receive a passport from their consulate if they have paid their taxes to their country (Eritrea and the United States are the two only countries worldwide to use a citizenship-based taxation). The passport validity is 5 years or less. Eritreans wanting to take another citizenship need permission from the Eritrean Government if they do not want to lose Eritrean citizenship.
