My family knows someone who does the 30/30 out of Port Harcourt. Flies into MMA and then to Houston, then a puddle jumper to Jackson or NO. His wife is begging him to go to your neck of the woods instead LOL.
I have worked with Nigerians here (and Russians, Koreans, Gabonese, Brits, Canadians, Kiwis, an Algerian, etc.). The oil patch is truly a global industry. Hopefully, our current contingent is going to maintain its present staffing...(all domestic).
