Start-up visa is issued for a period of up to 2 years, without the right to renew it, but with the possibility to switch to other types of work visas from the UK.
When switching from a Tier 1 Graduate Entrepreneur visa to a Start-up visa in the UK, you need to know that the period for which you can get a Start-up visa depends on how much time you have already spent in the UK under a Tier 1 Graduate visa Entrepreneur in such a way that the total time spent in Britain on these visas should not exceed 2 years.
If you are already a holder of Tier 1 Graduate Entrepreneur visa, you still have the right to bring your close family members to UK. To do this, you must apply for a UK Dependant visa.
You can no longer extend your Tier 1 (Graduate Entrepreneur) visa at the end of the first year. You must apply to switch to a Start-up visa instead.
