My online 90-day application was rejected for no apparent reason (I have successfully applied many times before and know all the rules). I read here that sometimes the rejection email contains an explanation of the reason. Mine doesn't, but there is a message saying "Please contact the nearest immigration office in person immediately". I just wanted to ask if this is a standard message in such an email, or if I should go there as soon as possible. My 90-day deadline is 6th April. Or maybe try to re-apply online again?
