I wouldn't want to give you the number, because that would be speculating. If you look at our approval rate of 86%, the remaining portion would be refused cases, but not necessarily for marriages of convenience. There could be other inadmissibilities or ineligibilities for the sponsor. It is a relatively small proportion, but it is fairly time-consuming for our office to make sure that we are able to assess each and every application fairly and in a timely manner.
