Sent N-400 , what is next ?

[handxx]

I sent my n-400 package through USPS priority mail on last friday. It arrived to Lewisville, tx. I checked from USPS website and the package was delivered at 1.35pm

My question is after they open my package, will they send me a letter for the case number or an e-mail ? I just wonder , how I will track my status ?

In a few days you will get a receipt notice in regular mail. You can track progress of your case online with the case number on the receipt notice. Online tracking is not very accurate though.
