The US has held one presidential election in Nigeria's four years of working in the country, and Nigerians are keenly interested in the results. The conduct and results of the election affect perceptions of the US and the longstanding relationship between America and Nigeria. The US foreign policy is formed by the president relying on input from all three branches of government, including Congress and the National Security Council. The US has consistently sought to work with Nigeria to improve economic stability, security, and well-being by strengthening democratic institutions, improving transparency and accountability, and professionalizing security forces. The US-Nigeria Bi-National Commission continues to enjoy a close association and working partnership with Nigeria on various issues, including good governance, rule of law, regional security, women's empowerment, education, healthcare, access to economic opportunity for Nigeria's youth, and countering violent extremism. Nigeria is Africa's most populous nation and a significant trading partner for the US, with bilateral trade exceeding $9bn in 2014.
