Erasmus Student Network Boğaziçi (ESN Boğaziçi) or Boğaziçi University Network of International Students (BUNIS) is a group of volunteer students from Boğaziçi University who strives to help Erasmus/Exchange students to enjoy their experience in Boğaziçi and in Istanbul.We were founded in 2009 as an ESN section by some Boğaziçi students who were really enthusiastic about starting a community which would help Erasmus/Exchange students about their stay and get as much experience as possible out of it. We became an offical student club of Boğaziçi University in 2012 and named BUNIS. Today we receive around 250 exchange students per year and work with a team of 80 volunteer students.
