I have a 3 month Non-Imm O (marriage) visa. Last year I extended it for one year. This year I want to extend it again. I went to the local immigration office with appropriate paperwork and after 4 hours got the 'under consideration' stamp which expired today. So today I went back to the office and they tell me the paperwork has not come back yet. I asked if I need a new stamp in my passport to reflect this and was told 'no' and that the 'under consideration' stamp is good for one month, despite the date on it.
Is this correct?
I am concerned that I technically do not have a valid visa now.
