Do I need a visa to travel to Ireland?
Whether or not you need a visa to enter Ireland depends on your nationality and the reason for your visit.
You can check if you need a visa here.
This Embassy only processes visa applications for residents of the United Kingdom who require a visa to visit Ireland. Non-EEA citizens with UK Biometric Residence Permission (BRP) who wish to travel to Ireland may need a visa to do so, as their BRP has no bearing on their permission to travel to Ireland.
You should also note that a Schengen visa is not valid for travel to Ireland.
