US Immigration from Egypt

Is it okay to renew the passport which was uploaded to the NVC?

Can I renew the passport and bring the new one and old one to the visa interview or will the new updated passport cause a delay since it's different from what was uploaded to NVC?

Ever since my June appointment was cancelled in April they told me to keep checking the site for scheduling another appointment, for the first couple of days I was able to with no problem until I checked it about 3 times one day and started getting this error, now it would be fine if it reset the next day or even after a while but...

It's been over A MONTH AND A HALF and I still can't check for appointments, I sent them 5 emails and got 2 automated replies with no info on how to fix it, I even emailed the embassy and the immigrant section and got no reply.

I've been trying to get a hold of someone to help me on the phone and it either puts me on hold or says I'm not calling during working hours ( when I am ). Please help we've run out of things to do and we can't get passed this error I've gone over a week without checking and nothing changed.

Hello,

I'm very confused. My mom got an appointment for IR5 interview in Cairo-Egypt that was scheduled by NVC, can anyone help me to prepare the documents that she will need to bring with her in the interview.

Thanks,

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 .

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