About Ireland Critical Skills Employment Permit
The Ireland Critical Skills Employment Permit is aimed at highly skilled workers in occupations experiencing a labor shortage, as defined on the government's Critical Skills Occupations List. Unlike most Irish work permits, it allows the holder to apply for family reunification and the spouse receives immediate work authorization. After two years, holders receive Stamp 4 permission, granting unrestricted access to the Irish labor market, and can apply for long-term residency after five years.

The UK Ancestry visa is an immigration route for Commonwealth citizens aged 17+ who can prove that at least one of their grandparents was born in the UK, the Channel Islands, the Isle of Man, or (before 31 March 1922) in Ireland. Holders may live and work in the UK for 5 years, then apply for Indefinite Leave to Remain (ILR), and British citizenship 12 months after that. The route is unusually generous in giving full work rights and a fast settlement clock without an income or sponsorship requirement.
