я навіть колись на пошту їх іммігр сервісу писав і от яка була відповідь:
Nationals of certain countries, including Ukraine, may travel to Ireland on
UK Short Stay Visas without the need to obtain a separate Irish Visa under
the Short Stay Visa Waiver Programme, subject to certain conditions. Among
the conditions are;
· The person holds a valid UK short stay visa, and has
travelled to the UK on this visa, prior to travelling to Ireland
· The person's visit to Ireland ends before the UK 'leave to
remain' ends
The maximum stay permitted under this programme is 90 days. Employment is
not permitted.
UK short stay visit visas for the following categories are not permitted
under this programme:
· Visitors in transit
· Visitors seeking to marry or to enter a civil partnership
Please note that this scheme does not apply to those holding a long term
permission for the UK, for example:
· Long term student visas
· Persons seeking to join a spouse or for family
reunification
