Update. We went back today and got our 60 day marriage extension. There was initial confusion as they wanted bank details etc but we made it clear we didn't want the year extension, only the 60 day extension as I'm back to work soon! Then they suggested we wait and see, but I insisted we wanted extension. So thanks for all the advice it really helped. It took just over 1 hour. Maybe the amnesty will get extended, but I'm happy to pay for the peace of mind.
