Visa approved and passport requested! Can't believe it was so fast!
About 2 weeks ago we received a similar email as schmuhahaha, asking us to send an Original police certificate. That's weird, we thought...We definately sent the original...So I sent the London Office an email through their webform explaining that we did send the original, but that if they wanted a new one we could easily accommodate them or give them the garda (police in Ireland) stations telephone number or anything else that might help. Sent the webform submission on Monday along with an upload of the photograph of the certificate (as we took photographs of every page of our application plus all additional documents, which I would recommend doing to anyone who hasn't already submitted their application, so much peace of mind). Then today my husband (the principal applicant) received an email saying he had been approved and requesting his passport etc. I don't know what the problem was with the police cert but it's not a problem anymore!
Good luck to everyone else and don't be discouraged if it takes longer for you to hear back. My husband and I had a very straightforward case, together over 8 years, married over 6 years and currently living together in Ireland so no question to our validation. Our application was also very well put together I have to say, I was VERY precise, made sure there was no problems or mistakes and submitted everything together, all payments, medicals, certs, everything, so keep your chins up guys. It will happen for you.
Love and peace to all
