Amnesties are unpopular; governments need to get tougher if they want to be reelected.  Amnesties are unpopular, in the UK for example 65% of the population wants tougher immigration laws, [1] and so most governments are unlikely to resort to them except as a last resort. Instead of granting an amnesty governments need to get tougher on illegal immigrants in order to find, deport and deter them. This would be a much more popular policy and could be achieved using better monitoring and communications between departments. For example in the United States the Inland Revenue Service knows where millions of illegals live and are employed as they know 600,000 people work under the Social Security number 000-00-0000, presumably many more were used different made up numbers. [2] This would therefore not only catch illegal immigrants but would help end misuse of Social Security and IRS identification numbers. There are also other tactics that can make illegal immigration more difficult and less likely to pay such as preventing illegal immigrants from obtaining drivers licences or, as in Tennessee, employers that knowingly employ illegal immigrants can have their business licence suspended.
