The UK Border Agency has announced its annual update to the occupation codes of practice for sponsored skilled workers, with an effective date of March 1, 2011. To sponsor a migrant worker from outside Europe under Tier 2 or Tier 5 of the points-based immigration system, employers must use the codes of practice to: (1) check the skill level and appropriate pay for the job; and (2) determine where in the United Kingdom the job must be advertised before it can be offered to a migrant worker. Employers also must consult the latest version of the codes of practice before issuing a certificate of sponsorship.
