That will be an amazing thing if they do accept application with signature more than 90 days old. Kindly do let us know when u receive ur AOR.Take my example, my first appl. was received sept 6 and they returned to me on dec 4. It had the same language as this poster 'kawaii'.
So when I resent it on dec 5 the signature /date on it was definitely more than 90 days old. If that 90 day condition was so important for a resent applicaiton they would have clearly stated so and asked me to send a new application. Instead they said that the old date will be used for physical calculation.
Thanks
