I have ILR since 2013. We are small family, couple and two children.
My youngest child is British Citizen by birth however my wife and elder child are on spouse dependent VISA of settled person and both of them Biometric cards says "NO RESOURCE TO PUBLIC FUND". Their FLR extension is due in few months.
I am claiming Child benefit for both Children and i know this will not have any affect on my elder child extension as i am claiming not the child and claim is in my sole name.
However, My question is about UC. I've never applied one but circumstances have changed. The controvertial opinions about it confusing me as i donot want to risk my child and wife extensions and ILR. I also know that i will have to make joint claim and need to give my wife detail and VISA conditions so they will disregard her at interview stage. But what about my children element as one is british citizen and other is on dependend Visa? i am confuse how this works without risking their extensions?
I would appreciate your experiences and advices. I hope i am able to put my question across. Should i claim UC or not if i should than how it works as my child and wife is on Spouse Visa? Child tax credits/ working tax credits no longer exist. Thank you for your time and advices.
