Background:
American citizen (only), wife and infant son (born in UK and now on a Tier 2 Child) American citizens (only).
I am applying for my ILR in the UK shortly, having been living and working on a Tier 2 general since November 2013.
I married my wife and she joined me in early 2016 on a Tier 2 dependant visa. We both extended in November 2016, and hold an extension good until November 2019. Thus, as of the time I am eligible for ILR, she will have been resident in the UK for a bit less than three years, and thus not eligible for ILR (as far as I know) -- this is the essence of my question.
Questions:
(1) Am I correct in my reading of UKVI's "Points Based System (Dependant) - Policy Guidance" that my wife is fine to remain on her Tier 2 dependant visa until its expiry (even after I receive my ILR)?
(2) To what visa should we be looking at moving my wife so that she will be able to apply for ILR after five years collectively. Probably pertinent: I intend to secure a UK Passport for myself and my son as soon as possible, so around the time of the expiry of her Tier 2 Dependant Visa.
Possibly related, but their circumstance seems more complicated: Tier 2 dependent children born in the UK
