Annabel Mace is a partner in our Labour & Employment practice group and leads our UK Business Immigration team. She has more than 20 years’ experience advising businesses across a range of sectors on all aspects of business immigration and employment law.

She has in-depth expertise in the Home Office’s Points Based System, particularly in relation to compliance issues arising out of maintaining sponsor licences. She also regularly advises clients on more complex matters (particularly where there is an immigration/employment overlap) such as:

  • The immigration implications of mergers, acquisitions and business restructures
  • Reinstatement of sponsor licences where they have been suspended or revoked
  • Illegal-working allegations where civil penalties have been (or are likely to be) threatened by the Home Office (and defending them, if issued)
  • C-suite hires and departures, including where visas need to be obtained urgently and/or there is an immigration-related challenge of a sensitive nature
  • Supporting employees whose visas has been curtailed or who have been detained at a port of entry
  • Cross-border projects and international assignments, including overseas remote working and the impact of Brexit
  • Immigration compliance programmes and audits

Annabel speaks regularly at seminars and workshops as part of the Labour & Employment Practice’s national seminar programme, as well as at bespoke client training sessions. She is also an updating author for immigration matters on the employment law website XpertHR.

She is an active participant in the firm’s pro bono initiatives.
