Timeline for Overstayed parent Resident app

[windrush]

We just mailed in my mother's applications I-130, I-485, I-765, I-864. I am a US citizen above 21 years of age. I wanted to inquire how long does it usually take to get a reciept number and first notice of them processing any of these applications. We mailed them out April 11, 2012 so just couple days ago. Any information would be thankful.

What form of payment did you send? Did you send the application using a trackable method?
