Change in visa type?

[hypermutley]

Hi, I am new here, hope someone can help.

Hubby is Irish, when i moved here i applied on non-EU family member visa almost 5 years ago.

A couple of years later, on further inquiry he found out that since he was born in the UK he is entitiled to naturalisation and now has a British Passport. I remained as non-EU family member visa.

My initial 5-year visa is expiring soon. What visa should i apply for as we plan to live here forever? I think EEA4 for Permanent Residency - despite the title of the form wording on the website says "Non-EEA nationals will be issued with an endorsement, which is placed in their passport. This endorsement is valid for 10 years."

But there is also the FORM SETM which i am now eligible for, but can i apply on this as my existing visa is the EU route?

Please help.
