Looking for a way to establish a commercial business in the UK? UK sole representative visa is the most appropriate way to do so. It permits a parent company overseas to open a subsidiary or branch in the UK. Once the application is successfully accepted, the applicant is granted 3 years of entry clearance. And this can be extended for another 2 years. If the applicant stays under this category for 5 years, the applicant qualifies for indefinite leave to stay in the UK.
