Hi, i filled i-485 application. my no was active for march. so that i send my document by sending them overnight so, that they can get my doc on 1st march. but when i track my number. it says that a notice was left because an authorized recipient was not available. You may arrange redelivery by visiting............... If this item is unclaimed after five days then it will be returned to the sender. Information, if available, is updated periodically throughout the day. Please check again later. so what does it mean i am so worried. if they received my doc than they will inform me or not??????
