How or where do I track my green card once I have entered into the US and dropped off my papers? I havent received a tracking number and the only numbers I have are my A-number and and my case number. They didnt give me anything in the immigration office where I dropped off my papers at POE. I got a stamp when I entered the US but I dont think there is a number I can use to track. I tried this website but it asks for a receipt number but I dont seem to have one: https://egov.uscis.gov/casestatus/landing.do I also tried calling the number on that website but theydont seem to be able to help me either. It has been 5 weeks now since I entered the US and I still havent received anything in the mail.
