Well they state on their website a maximum a month's decision time that is why we were getting worried. Also when I rang the embassy they said it was strange that nothing had been added to his case notes since the 2nd October and they hadn't acknowledged they had received the additional information they requested from us. They told us to send an email to the address we had received the request from.
Sorry I only started a second thread because it was different question.
Thanks for your response, we will sit and wait.
