Yes, all members of the family must originate from the same country; their travel documents must be the same type (e.g. normal, official, diplomatic); and their arrival date must be the same (Please note that the validity period of e-Visas will begin as of the date selected as arrival date. e-Visa holders can enter Turkey on any date within the validity period. In other words, all members of the family are not required to enter Turkey on the same day.) In addition, all prerequisites (if any) for e-Visa application must be met by all in the family.
