Do we need to provide old IRP cards for naturalisation?

I'm not too clear on this aspect. Older documents mentioned that passport stamps or IRP cards were needed but is this no longer necessary since it's all digitalized?

Or do we need to provide certified copies of past IRP cards and passport stamps?

And as a follow up, should they be certified if they have to be provided?

I don't think you needed cards/passport stamps themselves. When I was applying back in 2021, I never needed my IRP cards.

Besides, in some places they take them away.

No need to bother with those.
