It is great to hear you wish to return to visit the Emerald Isle to reaffirm that you might want to move here. Do you have a particular part of Ireland you most liked and could see yourself settling down in?
Citizens Advice has a great page on moving to Ireland
which is well worth checking out and will cover a lot of questions you have relating to the process of emigrating. You also mentioned working remotely, We have a great page on digital nomads
living in Ireland which may be of interest to you.
Let me know if you have any more questions, and I would be glad to help.
