Little bit lost here, need your advice. I have Spanish Blue Card, I am citizen of Russia, and I want to travel to Republic of Ireland. Do I need visa? As I understand that Republic of Ireland is not member of Schengen, but the member of EU. According to this I need visa, am I correct? http://www.citizensinformation.ie/en/moving_country/moving_to_ireland/coming_to_live_in_ireland/visa_requirements_for_entering_ireland.html
According to TIMATIC:
National Russian Fed. (RU)
Destination Ireland (Rep.) (IE)
Passport required. - Passports and other documents accepted for entry must be valid for the period of intended stay.
Visa required, except for Nationals of Russian Fed. with a valid "C" visa issued by the United Kingdom if they have first entered the United Kingdom for a maximum stay of 90 days or until the end of the period of stay granted in the United
Therefore the answer is yes, you do need an Irish visa. The only exceptions are for holders of UK visas, although having a valid Blue Card would make it much easier to receive an Irish visa.
