Thank you for your reply

. I filled in the application form and saved the doc to my google drive so I have the check list handy. For the place where you sign and attach the photos there is a list of only 7 professions...
“I certify that the applicant is personally known to me, OR She/he has been identified to me by
_______________________________________________________
who is personally known to me (delete as applicable) and has signed Section D in my presence. I also certify that the photographs (on the reverse of which I have Signed my name and written the date) supplied with this application are a true likeness of the applicant.
Member of the Clergy
Medical Doctor
School Principal
Bank Manager
Solicitor/Lawyer
Police Officer
Magistrate/Judge”
Then, as you say, on the website it’s just the long list. This is why I’m confused. I’m hoping my mum’s vicar, who is signing her passport copy, will also sign my form and photos. She has met me and has known my mum (who is my Irish citizen parent) very well for several years. I do understand that my mum cannot witness as she is related to me.
