"Ofisi za Uhamiaji"

Translation: Immigration Offices

[deactivated user]

What is the reason for the "za" whenever this phrase appears? It that what it is actually called in Tanzania -- Ofisi za Uhamiaji -- something like the U.S. Centers for Disease Control?

[machieng]

you can use both 'ya' and 'za', whose translation of course will correspond to 'office' and 'offices'.
