US Immigration from Nigeria

My husband's green card expires 12/19. We sent off his papers last month and the USPS tracking says it was received on 11/30. I put in an electronic payment as well as the E-notification form. They've not taken out payment or sent a notification of it being received. What should I do?

When I tried calling USCIS, they said I needed a receipt number but I don't have one so they can't give me any information.

I tried emailing Lockbox support but received an email stating "An inquiry related to a receipt notice for Form I-751, Petition to Remove Conditions on Residence or I-829, Petition by Investor to Remove Conditions on Permanent Resident Status will not be addressed, as those notices are not printed by the lockbox. The Lockbox has recently experienced a significant increase in filings. This, in addition to the restrictions put in place because of the COVID-19 pandemic is causing significant delays for processing receipt notices. USCIS continues to work hard to minimize delays."

What should I do? What if I don't get a notification before his card expires? Will he lose his job? Will he be out of status?

Should I resend? What if they eventually process both? Will they return the money from the first one?

The DMV made this license expire that day as well. How can he renew if his green card is expired?

Hello,

Has anyone heard anything about appointments being rescheduled that were cancelled by the Nigerian embassy due to COVID? Or, about appointments for those who were DQ'd prior to April 2020?

I want to make enquiry regarding immigrant visa for f1...My interview date was scheduled 31th March 2020. But, was cancel due to the global Pandemic.. ..

I will appreciate it if I can get information on when my interview is going to be rescheduled..

Does the applicant need to take original documents of petitioner to interview?

Me and wife withdraw a case and case was denied. Then USCIS informs that when I filled I was present in the US contrary to law and I have 33 days to leave
I currently have an L1 status approval with a1-94 that runs from 2019 to 2022. I applied this year for AOS.

Already spoke to a lawyer and they say it s a generic letter they send out after denial. I also don t have a visa for this status because I never needed to leave the US.

Really confused on what to do. Anyone with such experience or could this be something unrelated to overstay.
