Article 4U.K.Single application procedure
1.An application to issue, amend or renew a single permit shall be submitted by way of a single application procedure. Member States shall determine whether applications for a single permit are to be made by the third-country national or by the third-country national’s employer. Member States may also decide to allow an application from either of the two. If the application is to be submitted by the third-country national, Member States shall allow the application to be introduced from a third country or, if provided for by national law, in the territory of the Member State in which the third-country national is legally present.
2.Member States shall examine an application made under paragraph 1 and shall adopt a decision to issue, amend or renew the single permit if the applicant fulfils the requirements specified by Union or national law. A decision to issue, amend or renew the single permit shall constitute a single administrative act combining a residence permit and a work permit.
3.The single application procedure shall be without prejudice to the visa procedure which may be required for initial entry.
4.Member States shall issue a single permit, where the conditions provided for are met, to third-country nationals who apply for admission and to third-country nationals already admitted who apply to renew or modify their residence permit after the entry into force of the national implementing provisions.
