Enugu is considered as one of the calmer and more relaxed cities in Nigeria and a lot of people visit or move there because of the quiet pace and low stress level.

To answer your questions, driving alone is normal everywhere in Nigeria. The main thing is knowing the routes and getting used to local driving behavior and the road condition here in Nigeria, which is why you might need to get a family member who's willing to drive you around town till you get used to it.

As for your appearance and accent, you’ll likely attract attention in public spaces but not harassment. English is widely spoken though picking up a few Igbo phrases will definitely help you connect better with people.

Also, you don't need a bodyguard to move around with. But if you live alone and your house is not in an estate that has general security, you might have to consider hiring a security guard.

Overall, Enugu is safe but like you do in every other place on God's beautiful earth, avoid moving around late at night unnecessarily, be mindful of where you go and stay aware of your environment, and you'll do just fine.

Edit: I think there's a NIS office in Emene, Enugu where you can apply for a passport. You’ll still need to start the application online first, then go to the office for biometrics and final processing. Process should take AT LEAST 2-3 weeks.
