Yes, in most cases, a UK Biometric Residence Permit (BRP) does not grant you visa-free entry to the Republic of Ireland. Because Ireland is not part of the Schengen Area and maintains its own immigration rules separate from the UK, your right to stay in the UK does not automatically extend to Ireland. However, there are two exceptions in 2026: if you are a citizen of a country that is "visa-exempt" for Ireland (like the USA, Canada, or Australia), you don't need a visa regardless of your UK status. Secondly, if your country is part of the Short-Stay Visa Waiver Programme, you may be able to visit Ireland without a separate visa only if you have a valid UK "General Visitor" visa and have already cleared immigration in the UK. Those "living" in the UK on a long-term BRP (like a Work or Student visa) usually still need to apply for a standard Irish Visit Visa, though the fee may be waived for certain nationalities under the waiver program.
