The UK Innovator visa has an 85% success rate, and a properly prepared business plan has a 90% chance of receiving endorsement.
You do not need to engage with a pricey solicitor or consultant who will give you generic advice and try to upsell you a business plan writing service.
The initial step is to get endorsement from a government authorized endorsing body, who will want to see a business plan that is written specifically for innovator / start-up visa purposes. Once you have received the endorsement, file the required form online and wait for a decision. The decision usually arrives within three weeks.
A business plan is a key component in obtaining an endorsement, which is why I offer a more cost-effective alternative to using a solicitor who will give you generic advice and upsell the same service that I provide.
If you like to get the endorsement, I will be happy to help.
