This question already has an answer here:
I came to the UK on Tier 2(General) Visa on 26 April 2014. My wife and Daughter came along with me on Tier 2 (Dependant) Visa. Initial visa was valid until 31 January 2016. In December 2015, I have applied for a 3 year extension for all of us and got extension until 14 Feb 2019. I qualify for my ILR on 1st May 2019 which is 75 days away from my Tier 2 visa expiry date. So I am now planning to apply for an extension to my Tier 2 Visa.
We had a baby born in the UK in Feb 2017. As I was not intending to travel out of the UK with the baby, I had not applied for a Tier 2 (Dependant) Visa for the baby so far. Now that I am applying for an extension to my Visa, Do I need to apply for a visa for the baby as well? Is it legal not to apply for visa for the baby?
As I am planning on applying for ILR in May 2019, I want to find out if I can get away without having a tier-2 visa for the baby?
