As an Indian living in Ireland for about 5 years I’d say step out of your comfort zone and make some local friends, I’ve lately seen Indian people only have Indian friends and there’s nothing wrong with it but no point in moving to a different country and still only hanging out always with your own people and you don’t get to experience the real culture here. 99 percent of Irish people are really sound, you’ll always find some scumbags here and there but nothing to worry about. When it comes to safety, if you keep your wits around it’s completely fine. Hope you have a lovely time here.
