Foreign nationals seeking opportunities to serve in a foreign military can apply to join the armed forces of several countries, although eligibility depends on nationality, immigration status, military experience and the recruitment programme available. Countries such as France, the United Kingdom, Australia, Canada, Spain, the United States, Ukraine, Russia and New Zealand have provisions under which certain foreign nationals can serve in their armed forces. Israel also operates a special enlistment programme for eligible foreign volunteers. However, the rules differ considerably. While some countries accept foreign applicants without requiring permanent residency, others restrict recruitment to citizens of selected countries, permanent residents or experienced military personnel. For Nigerians considering military service abroad, understanding these differences is essential because being eligible to enlist does not automatically guarantee a visa, admission into the armed forces or permission to settle in the country. Here are nine countries, alongside Israel’s special volunteer programme, where foreign nationals may be eligible to serve in the military. 1. France France is among the best-known destinations for foreigners seeking to enlist in a foreign military through its French Foreign Legion. The Legion, a branch of the French Army, recruits men of different nationalities and allows eligible foreign nationals to apply without first becoming French citizens. According to the Legion’s official recruitment website, applicants must generally be older than 17 and younger than 40 when they report to a recruitment office. Candidates must also meet medical, physical and administrative requirements. Applicants from outside the Schengen area must present a passport, although the Legion does not arrange visas or exit authorisation on behalf of recruits. Unlike conventional recruitment into many national armed forces, the Foreign Legion has a specific recruitment system designed to accommodate foreign nationals. 2. United Kingdom The United Kingdom recruits eligible foreign nationals into its armed forces, including the British Army, subject to nationality and recruitment rules. Eligible applicants can include citizens of Commonwealth countries, a category that includes Nigeria, as well as Irish citizens and certain other groups. The British Army has historically recruited Commonwealth citizens and operates the Brigade of Gurkhas, which recruits eligible Nepalese applicants. However, Commonwealth citizenship alone does not guarantee admission. Recruitment availability, residency requirements, age limits, medical standards and the specific service or role can affect eligibility. The UK Ministry of Defence has also operated limited recruitment arrangements for Commonwealth applicants in specialist roles. Consequently, prospective applicants should check whether applications are currently open before making travel plans. 3. Australia Australia allows certain foreign nationals to apply to join the Australian Defence Force (ADF). Under eligibility arrangements introduced in 2024 and expanded from 2025, eligible permanent residents from the United Kingdom, the United States and Canada can apply. Eligible New Zealand citizens living in Australia can also apply. Applicants must satisfy additional requirements, including residency conditions, medical and physical standards, security checks and relevant citizenship rules. Australia also has an overseas lateral-entry pathway for eligible personnel with previous military experience whose skills can be transferred to the Australian Defence Force. This means Australia is not an unrestricted destination for anyone seeking to join a foreign military. Nationality, residency and previous service can determine whether an application is accepted. 4. Canada Canada permits eligible permanent residents, as well as Canadian citizens, to apply to join the Canadian Armed Forces. This creates a potential route for foreign nationals who have already obtained permanent residency in Canada. However, applicants must satisfy the armed forces’ recruitment conditions. The official recruitment website specifies that permanent resident applicants must provide evidence of three years of physical presence in Canada. Age, education, medical fitness, background checks and the requirements of the selected military occupation also apply. Therefore, Nigerians hoping to enlist in Canada generally need to establish the required immigration status and meet the applicable recruitment conditions before they can join. 5. Spain Spain allows certain foreign nationals to compete for places in its armed forces, particularly in enlisted sold
