ILR Eligibility for spouse- Changed Visa Type

[Jackman]

Dear Experts,

I have a unique situation (I think):
Situation: I have been on a Tier 2 General visa and will be eligible for ILR visa in May 2017. My spouse came to UK in April 2012 on a Tier 2 ICT , staff migrant visa. However, her visa was changed to Tier 2 dependent in February 2013 and she has been on a Tier-2 dependent visa ever since and we have a son born in UK who is 2 year old now (on a Tier 2 dependent).

Question:
1. Is my wife eligible to apply for an ILR along with me? If not, does her visa need to be changed to ILR dependent after I get my ILR (she has tier 2 dependent visa until 03/2018)
2. Can I apply for ILR for my son? if not, does his visa type need to be changed after I get my ILR?

Any help will be hugely appreciated. Thanks.

No, she does not qualify with you. She can continue on her existing visa till she qualifies for ILR in 2018. No need to change visas.

2. Can I apply for ILR for my son? if not, does his visa type need to be changed after I get my ILR

?
Once you have ILR you can register your son as British. He does not require ILR for this.
