I'm M25 from the US, I do 3d media production and carpentry. I had a child with a UK national and both mother and child are also here with me. Unmarried but cohabitating for two years. We have researched pretty thoroughly how to gain citizenship here, but I still can't find any information about whether or not a US citizen needs to have his own medical insurance in order to gain residency (which of course leads to citizenship within 5 to 6 years).
Is there anyone from the US here, or anyone else know the answer to this?
I'm also wondering how to obtain an FBI background check, if that's necessary. I've read elsewhere that you need one. Anyone from the US received this document and went through this process?
