We are a family of five, separated by my husband being a U.S citizen and after living together for years here in the UK a change in law meant my husband was made to return to America. We had no choice other than to apply for visas to reunite with him. We started saving.for the costs and selling things we owned once he had left back in April (1st) 2013, our youngest son was 17 moths, we are hoping to send the ds260 once the nvc correct an error in prefixing the nvc number of mine with auk.( Auckland New Zealand) instead of LND London. A muddle up which may of been caused by the fact that I was born in Auckland but flew back to the UK as a young baby, finding it extremely hard to actually have a response or indeed find.any help or get through on phone lines to either uscis or nvc.
