The question is what happens then? Do we immediately deport all these newly found immigrants despite the large cost? Would the occupation they are engaged in or having made a family make a difference? Finding or knowing where illegal immigrants are is not the same as getting them out of the country, in the UK in 2006/7 20,700 people were recorded as failing in asylum requests but the UK only managed to deport 18,280. [1] Finding more illegal immigrants would mean the deportation systems could not cope.  [1] Johnston, Philip, ‘Number of failed asylum seeker removals falls’, The Telegraph, 21st August 2007,
