In order to provide an opportunity to join the Defense Forces of Ukraine, the Center for Recruiting Foreigners and Stateless Persons operates in Ukraine, which is subordinate to the Ministry of Defense of Ukraine.

Applications to join the Ukrainian Defense Forces are submitted by foreigners on the website joinuarmy.org. The website is available in English, French, Spanish, and Portuguese.

When submitting an application, a foreigner fills out a questionnaire in which he/she must indicate his/her name, surname, date of birth, citizenship, information about language skills, place of residence, other necessary data and attach a scanned identity document or a high-quality photograph. When filling out the questionnaire, the candidate can choose the unit in which he/she wishes to serve in the military. This option is not mandatory. The list of military units that have the ability to recruit foreign citizens, general information about them and current vacancies can be found on the website joinuarmy.org.

After receiving the application, the recruiter of the Center for Recruiting Foreigners and Stateless Persons contacts the candidate within a few days and conducts a video interview. During the interview, the candidate's identity is confirmed, his/her motivation and willingness to join the Defense Forces of Ukraine are revealed. Also at this stage, the candidate's financial ability to independently pay for the transfer to Ukraine is clarified. The recruiter also answers all the candidate's questions regarding the specifics of the service, provides information on the general features of the logistical route, visa policy, etc.

If a foreign citizen expresses a desire and has the opportunity to join the Defense Forces of Ukraine and is ready to arrive within next two months to the territory of the state with the goal of joining the Defense Forces of Ukraine, his/her preliminary check is carried out. If the foreign citizen passes the check, an invitation letter is generated. The invitation letter has a unique number, it indicates the personal data of the foreign citizen and the contact phone number of an authorized person who can confirm or deny the authenticity of the letter.

During the trip to Ukraine, the recruiter of the Ukrainian Army Recruiting Center remotely accompanies the candidate until he/she arrives at a designated point in Ukraine and provides him with information and consulting assistance. After arriving at the designated point, the candidate begins the registration process. He\she receives a TIN, passes a medical check and a special background check, etc. If the candidate meets all the criteria, he\she joins the Ukrainian Defense Forces in the unit designated by him. Later, he\she signs a contract and undergoes basic general military training at the designated training center or military unit and serves in the selected unit.
