second wall
n.— «Mr Tsao pointed out that in addition to the stress of having to pass the exam, there is the financial hurdle: naturalisation currently costs $US400 ($A506) to complete, and may rise to $US800 under current proposals. His group and other immigration organisations have taken to calling the citizenship test “the second wall”. The first wall is the physical structure being erected along 1120 kilometres of Mexican border to keep out illegal immigrants.» —“Testing times for those seeking US citizenship” by Ed Pilkington in New York City The Age (Melbourne, Australia) Dec. 2, 2006.
