Even interns of citizen it’s Somali citizen I don’t understand where Somalian citizen comes from maybe from your own pocket?Somalian = Citizen of Somalia
Somali = An ethnicity.
All Somalis are Somalian but not all Somalians are Somali.
If you are describing people from Somalia, you say Somalian. If you are describing an ethnic Somali community, you say Somali.
