  This study explores the deflection angle of photon rays or light-like
geodesics within the framework of Eddington-inspired Born-Infeld (EiBI) gravity
background space-time, taking into account the influence of cosmic strings. The
primary focus lies in deriving the effective potential of the system applicable
to both null and time-like geodesics, as well as determining the angle of
deflection for light-like geodesics. Our analysis shows that the presence of
cosmic strings induces modifications in these physical quantities, leading to
shifts in their respective values.
