US Immigration from Egypt

Greetings ,

I did submit the requested files on CEAC , Everything got approved and completed . However i was asked to replace 2 items out of 6 ( Birth certificate - Marriage Certificate )
I did replace them on march 2020 , and their status are submitted since then and never got changed .
Any Help regarding that please cause i have no clue what is going on there .

Public Charge Final Rule
I am applying for my parents, what is the Public Charge Final Rule?
Do I have to do anything about it?

I am submitting I485 for my parents. Do lockbox facility accept certified checks?

Do I need anymore documents for filling the I1-30 for a widow mother rather than my translated birth certificate, her translated birth certificate and her foreign passport?
Is there anything else

For the siblings, is the same my translated birth certificate, her translated birth certificate and her foreign passport?

Is that it?

Some people I know keep saying that they got an appointment date however the embassy didn t announce that they re open yet

Does anyone know if they resumed working on the cases they have?

also i know that it could be a repeated question but does anyone know when are they opening?

Also is there a group conversation for Egyptians where they share any updates about the embassy and the interviews?

thanks in advance
