I am on a Tier 2 visa and going to apply for ILR in July. My wife was on a student visa and my son, born in tje UK (he is 5 years old now) was her dependent. I changed both my wife's and son's status to Tier 2 dependent about two year ago. Can I apply for my son's UK passport? I still have a Tier 2 visa until 2019. Can I only apply for ILR and leave my wife as a Tier 2 dependent?
If not, can I apply for ILR dependent after getting my ILR status?
