Spouse visa - letter of support

Hi,

I'm a British citizen and I'll be applying spouse visa for my wife in about couple of weeks time. I'm self-employed and I earn over £21,000 after all expenses, Got all the required documents ready to submit. My question, Do I need to mention about my SE in the letter of support? like the nature of the SE, how much I earn etc etc..?

Thanks

A sponsorship declaration will suffice for this purpose

This will be covered in the Appendix 2 document. You can also add information in the last section of this form for additional details if you would like to mention something not covered by the previous questions.
