Hi Ron and Sandy,
It's wonderful to hear that you wish to come over and see us for such a long time, there certainly will be plenty to keep you busy!
Where on the island of Ireland is Sandy's family from?
As a US passport holder you can indeed stay up to 90 days, all other stays are classed as long term stays and require a Long Stay "D" visa.
The criteria for which is to study, work or stay with a relative already resident in the Republic of Ireland. For further information, you may get in touch with the US embassy in Dublin
The rules for the UK are slightly different in that you can stay for up to 6 months without a visa
as a US passport holder. This includes Northern Ireland as part of the UK.
With regards to accommodation, please have a look at our approved accommodation
search page for some information. I have pre-selected self-catering as the type, simply enter in a destination to find what is available in the area.
I hope this helps and maybe some of your fellow members or industry partners will be able to add some advice too!
If you need any more help, just let me know!
