Tier 1 Enterprenuer to Exceptional promise

[SarjanNartan]

Hi all, following this forum since long. It’s been great thread to see all cases and positive outcome. Thank you to all for posting, replying and guidance provided by experts.
I have one general question that I have entered in UK on Tier 1 Enterprenuer Visa. Just wanted to find out my visa due to extend in October 2018.
But I have found about another route that is Exceptional talent/ promise. I consider my self as promising artist and I have got backgound of dancing career since more than 30 years and also at the moment I run dance school business on visa I granted. I have got all eveidence required for Prominsing artist category.
so can I get guidance that I can still can be eligible to apply for that as I have got few months to apply for extension . So what do you suggest.
And has anybody applied through Art Council UK. So if I can get guidance on preparing documents for stage 1 & 2 will be really appreciated.
Thank you in advance.
