I wrote directly to my MP (Lady Sylvia Hermon UUP) and recieved this reply today.
"Re Lance Corporal Gyanendra Rai (retd) UK Visa
Thank you very much indeed for your email of 17th June outlining your concerns about the difficulties being experienced by Falklands veteran Lance Corporal Gyanendra Rai in obtaining a UK visa.
Let me say straightaway how very grateful I am for the trouble you have taken to bring your particular thoughts on this matter to my attention and I shall certainly ensure your concerns are raised at the very highest level.
With this in mind I have already written to Lord Triesman,the Foreign and Commonwealth Office Minister with responsibility for the UK VISAS agency,reinforcing the points highlighted in your correspondence.
As soon as I recieve a reply from the Minister,I shall of course write to you again......."
I will keep you posted.
