US Immigration from Somalia

Hey guys, I need an advice. It has been more than 14 months since I had my K1 visa interview, I've been in administrative processing ever since, the main problem I have is the passport I applied with which was Somali passport. Somali immigrants got alot of scrutiny under Trump since it was part of the banned countries.I can apply for Ethiopian passport

I have medical licensing exam which I need to take in the US which allows me to apply for Tourist visa for that purpose, but I don't think I can apply the tourist visa with my passport if the K1 process doesn't end in time. So I have the option to apply for Ethiopian passport but I don't know how that will affect my application and overall even when I get it, if I can apply a visa with my other nationality while this process is ongoing. What do you guys think? Any input is highly appreciated.
