We moved into the processing stage last week on 14 April the day after documents were scanned in as “received”. Considering they had been signed for a month previously we were relieved (first passport application from overseas, including foreign passport which would have been expensive to replace if they’d lost it!) It looks like there is a lot of variation – some people move to approved after a few days, while some take longer. In our case there is a document which will need to be used for both applications and I’m not sure whether that will delay things or make no difference.
