Two questions, does Irish residency give you permission to travel to mainland Europe without needing a visa? Secondly does the Irish residency give you access to the United Kingdom in terms of tourism or in case you want to purchase a vacation home?
Irish residence permission does not give you extra abilities to travel through Europe. Visa requirements will still be based on your passport nationality. While the UK allows holders of some Irish visas to enter the UK without an additional UK visa, this does not currently apply to Irish work/study visas.
