Yes I am a US citizen.
I am in the UK on my own visa, and as stated this is for Self-Employment income. I do not have an employer to provide a Certificate of Coverage.
The only UK Certificate of Coverage I can find one where UK employers are sending employees to work in other countries. I do not fall under that scenario.
EDIT: I see some valuable and helpful instructions in that link that specifies who I should write to in the UK in order to obtain a Certificate of Coverage. I think that may be exactly what I was looking for!
