After you send your Form N-565 application to USCIS, they will start processing it. Shortly you will receive several notifications from USCIS concerning your application. But you may not get an immediate answer from USCIS.
The first notification is the receipt notice.
A Receipt Notice
USCIS will inform you that they received your Application for Replacement/Citizenship Document (the Form N-565). They will mail you the receipt notice at the mailing address provided in your application form http://us-immigration-info.com.
