My wife's fiancé visa (temporary leave to remain for two years) expired on 16th September 2013. We submitted at extension later than intended as the post office was closed due to strike, which reached the the home office on 15th October 2013. We have received a letter stating refusal to grant leave to remain as it was one day over the 28 days grace period. My wife is over 3 months pregnant and I have only travelled to USA twice in 10 years for no longer than 2 weeks on either occasion. My wife is part time employed and I am employed full time. We also have joint mortgage. what would you advise as moving to the USA is not a viable option.
