I am a naturalised citizen , originally from the UK married to a Texan. I am currently filing petitions for both of my British parents concurrently who both live in Cyprus. I came to the US in 2003. My husband filed for me when he lived in the UK and it only took 4 months and I cut out the middleman, so this long wait for the NO2 is new to me. My US citizenship was surprisingly quick and was applied for here in Dallas and took just shy of three months in total from start to finish, very painless and efficient.
