The worldwide economic downturn has caused a backlash against immigration in many countries.  The UK has proposed a new citizenship law, that would require prospective citizens to earn points based on their integration into the community.  Yet, the immediate concerns over the burdens imposed by immigrants often is ill founded.  A recent study by economists at University College London finds that immigration to Britain from the Central and Eastern European accession countries are net contributors to the budget!  Even though their wages on average are lower than native workers, their higher labor force participation and lower propensity to claim benefits results in this positive balance.
