Also, what does it mean if the online status writes like this:
Your I181 CREATION OF RECORD OF LAWFUL PERMANENT RESIDENCE was received on February 8, 2005. We mailed you a receipt with information about processing. It is taking between 30 and 60 days for us to process this kind of case. We will mail you a decision as soon as processing is complete.
What's I181? I am confused. Thanks in advance.
