Question (style of author is kept): i am submitting under exceptional talent route. Am proposing a business plan. but i have not created any website etc.. yet. i just have my plan and thoughts on paper. Do you think i can go ahead submit or wait and design website submit later?
Answer: I suggest that having a website of your idea (startup) is quite good thing. I know that during the Endorsement Process the Endorsement Panel of Experts is reviewing details of every application. Hence, a website can create a visual understanding what are you doing and expecting for.
However, I need to say that we should not overestimate the importance of the website or landing page. Having a strong application (recommendation letters from the C-suite managers of well-known companies, reliable supporting documents, confident personal statement) – these factors are more important.
In my personal experience when I applied, I wrote about a couple of my projects. But I had a landing page only for one of them. Hence, I cannot say “yes” or “no” to your question. It really depends on many factors.
Anyway, re-phrasing a famous song: “Listen to your heart when re-reading your application” and you will decide is it enough information about your project in the Tier 1 Exceptional Talent Visa application (including the business plan you have mentioned) without a website or you need to make a referral to the additional page in the Internet.
I hope my thoughts will help you a little bit.
