Citizenship after Surrinder Singh Route

Hi, I wanted to know how long my husband will have to wait to get citizenship. I am a British citizen and I exercised my rights in Ireland. We have recently applied for a resident card. My husband is a non-EU national.

I have read on the HO website but I'm still confused. It says family of EU citizens have to apply after 5 years and possibly one year of ILR (which is PR). But it also says if your a family of a British citizen you can apply after 3 years.

So am I right in thinking we can apply after 3 years? If not, can someone please explain it to me Thanks!

He'd need to be settled in order to naturalise, so after 5 years, subject to the other requirements.

So can he apply directly after 5 years or will he need to apply for PR?

Either way, however, if he has a PR card it ensures that his application will not be refused on the basis of being settled.

Okay thank you very much for your help Is there anything I need to have to prove 5 year residency for PR? I know I have to submit all the same docs as EEA2 but will he need to add any other proof for citizenship?
Just making sure! Thanks again..

Just what is required as per the form/guidance notes.
