US Expat paid in local currency questions (Addis Ababa)

Hi everyone. I will be relocating to Addis at the end of this month with my new job. I will be the first person they post overseas so in some ways they are learning the processes of relocating an employee with me. Initially, I was told I would be paid in US currency; however, they recently informed me that they will need to pay me in local currency in order to legally employ me in Addis.

Has anyone experienced something similar? Can you provide me with some insights on the pros and cons of being paid in local currency? Anything I should definitely bring up/negotiate with my employer? Please help!
