US Immigration from Nigeria

Hello- So my husband and I just received our interview letter from the NVC. His interview is scheduled for January 5th, 2021. As we are trying to get everything set for the interview next steps we are running into an issue. The first step on the prep list states that we need to create an online account at: http://www.ustraveldocs.com/ng/

However, when we go on the website to register it shows an error message of: Your request cannot be processed at this time and user could not be created . I attached an image for reference for what we are seeing.

Second, we have called the approved medical professionals for his exam and they all say to call back daily for a spot/ possible cancellation. Otherwise the soonest they can set an appointment is for after the interview date has occurred. Which is obviously an issue.

Any suggestions on how to deal with the above issues? Everything else on the next steps list we can easily get done.

I will be filing my own petition for my spouse to come to the US. The new process is to file the paperwork online at USCIS.

Do I need to upload the financial support paperwork now or wait until they ask me for them?

Hi guys please we need help we are calculating our household size in Part 5 question.

It's just my Husband and myself making it 2 but when adding together Part 5 items numbers 1-7 should it be 2 or 3 as we are getting 3. As Part 5 questions 1,2,&3 are 1 each making a total of 3 household size. We don't know if we are making sense. We are a bit confused. Please help. Thanks

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