hi anyone knows if my application is returned back can i resubmit the same forms knowing nothing has changed since i last sent my application like all the forms r still the same..how old can the signatures be? n r the signatures acceptable if its 90 days old since application was recevied or is it 90 days when they reopen my file ? the letter they sent me does have an application no on it but i used that in my ecas nothing comes up..
