Hello, we are family of four got PR in October 2016 via Tire 2 route. Now planning to apply for BC and then Passport. Unfortunately I lost my old passport that had the original UK visa with which I entered this country. That passport expired almost 4 years and half ago. I was using my new passport. ...

I also live in NI. There is no real border for immigration check between NI and ROI. Please move from both side like you travel between two citites of one country...
