I started this back in November 1999 when I applied for my K-1 visa, that all happened very quickly - about 3 months from start to finish. I moved over to the US in March 2000 and married my sweetheart in April 2000, my eldest son moved here from England to live with us in 2003.
I could have done the citizenship thing a long time ago but it never seemed to worry me, however I am excited about getting it done now - I have applied for my citizenship at the same time as my eldest son, we are hoping to get the interviews and oath at the same time :)
