Hi there my mother (South African) recently travelled to visit me in N Ireland and arrived in Dublin with her Uk visa in her passport. She was given great trouble at immigration in Dublin airport and threatened with being sent back . She was alone and in a wheelchair and eventually allowed entry with a warning to never do this again! She has previously traveled the same route many times with no problem. Was also told she had to activate her visa for the Uk... Just wondering if anyone else has had the same issue recently?
