I-130 Phoenix Lockbox No response for G-1145

[vnellai 0]

I am a US citizen.  I just filed 10 days back I-130 petition for my married daughter (above 21) by mailing it to Phoenix lock-box by FedEx and had attached completed G-1145 form too. FedEx tracking says it was delivered overnight promptly to the USCIS Phoenix designated address.

However, I haven't got any acknowledgement or response to my email-id or mobile phone (text) as mentioned in the G-1145 form? Any idea how long it takes these days just to get ack receipt of our I-130 petition filed?
