“Where a foreign national working in the United Kingdom applied late to be registered under the Accession (Immigration and Worker Registration) Regulations 2004 and his worker registration certificate was issued three months after commencing employment and covering only nine months of employment the certificate did not have retrospective effect so as to qualify him, under regulation 2(4), to claim the benefit as ‘legally working’ in the United Kingdom for 12 months for an ‘authorised employer’.”
