When do they finish sending out receipt notices?

I applied for RP/AD… my OPT expires in lesd than 2 months so I need to know asap if Im selected or not. When do yhey finish mailing out the receipts?

Don’t tell me you shouldve done PP. I didnt because my employer wrotr a check to USCIS Save program… for the combined fer for premium and base filing fee. I wasn’t gonna risk my chances

Historically they have sent receipts through June.
