Hello ,

May I please ask some guidance. I’ve settled status and will applying for naturalisation soon ,

1- I don’t have continues 5 year P60 or bank statements ( most of bank statement online) ( I’ve been working since 2008 for same company full time )
2- do I need to send any physical documentation or everything will be only ?
3- apart from my job , I’ve my own company as well which isn’t doing well but can I use anything from it to prove residency like assessment or accountant letter . It is LTD company
4- if any one please direct me to topic or list what documentation do I need as an settle status holder .

Thanks
