National Insurance Number NINO Self-Employed Rejected 8 time

[aposto]

Hi all,
I am working as self-employed (since October 2016), director of my LTD company. I've applied to Ni Number 8 times now and got rejected 8 times. I've got 5-6 different clients, 18-20 invoices, investment documents, insurance documents, all the other documents (total ~100 pages). I've sent all those documents in my last application. For that last application I was able to reach Glasgow Ni Number Centre people, they told me I am not a self-employed person cause I am paying my self a salary and working as Director means being an employee. What does that mean?! I know HMRC has a weird definition of 'self-employed' which doesn't allow you to work as a director of your own company. But my work visa allows me to do so (it is already there in my work visa application document, which I've provided as an evidence attached to the application).

My advisor tells me there is an issue with the updated definition of 'self-employed' of Home Office and HMRC, she says HMRC updated the definition on March 2017. Which means they will not give Ni Number until those definitions are changed or I need to work as sole-trader to get Ni Number (which is not possible because of IT contractor market).
I will apply for work visa extension (ECAA Turkish Business Person Visa) and not having Ni Number will impact the extension decision.

Do you have any suggestions? Is any of you having the same problem currently?

Thanks,
