My situation is probably a bit harder.
I am switching from PSW (which runs out in January next year).
As the rules are changing, I should apply before 5 April.
To be honest, I am pushing myself to the limits in terms of work, and family relationships to be able to do so.
I am not sure about the letter from the accountants. I called UKBA and talked to a solicitor who is helping me with the application. From what I understand, if you are in salaried employment you are not required to submit the letter from the accountant.
I was also advised by the solicitor to keep the application simple, and not to confuse a case worker with loads of unnecessary information. So I am not submitting a certificate of incorporation and or any other statuary documents.
If you do not have "some one" to sign a letter (this is also my case), I was advise to hire somebody on a part-time basis (i.e. a company secretary, HR manager, of financial manager) who can verify your earnings and your position in the company in a letter. This person should be officially employed by your company to do the job. This is what I was advised to do.
Anyway, it is encouraging to know that I am not the only one working hard to live in this country. Although, at times I wonder does it worth it...
What is your company's business? It's just a question, you do not have to answer.
