I got same as you, same letter. They understand the letter in English. It is a great help. I am to go back on the 15th, but I will try sooner, as I need to change to a non-imm if possible. If I wait till 15th it is too late, as the stamp will be till the 26th Oct.
Thanks Tod. I am on an extension based on being married to a foreigner who works here. Thanks for the advice. I will get on the case now and see what I can do. All the best.
