I applied in November 1st week 2018 for my wife. We had straight refusal on 5th Dec. The reason were... no joint bank statement, no proof of financial support or liability and shared assets etc. No support from friends. CO was Kimberly! Nasty bitch! Giving us so much pain in our life I can't explain.
I had uploaded marriage certificates, pics of wedding and reception and pics from honeymoon. Also had uploaded some screenshots of our whatsapp conversation. We still had refusal. We had no financial documents as we were newly married and our marriage was semi-arranged type.
I have applied for the same visa for my wife again mid Jan 2019. We had CO, Sophorn, contact on 14th Feb, requesting for Birth Certificate and Evidence of Relationship again. We had submitted so many proof of relationship this time from social media, from wedding, all whatsapp conversation, gifts, financial support (money transfer), 888 form from 3 friends and the list goes on. Also he said, IELTS was expired although it was only 18 months old. Its stated IELTS should not be more than 12 months old.
Anyway, we submitted again what he asked for, but we have no answer so far. We been away 6 months now. Honestly it's a joke. I have lost so much money, faith, time and patience.
To summarise the rant, I just want all people out there to submit all proofs of relationships as much as you can. Take no chances! We have suffered and we are still suffering.
