US Immigration from Nigeria

Good evening to everyone on here,on my my ds260 I was asked for my Instagram page I add my Instagram name instead of my Instagram username I thought it was the same so I Gave my Instagram name I hope this is not a red flag for me.

I did change of name two years ago. My surname is ISA but had always been written and used wrongly as ISAU even till university. So, two years ago, I decided to change it to ISA. Did court affidavit. My new surname ISA is on my passport and marriage certificate, even my wife and my daughter are ISA. My concern now is, at the interview, I might need to provide documents that have my former surname on them, even my drivers license still has my former surname. Wouldn't there be any problem as I have the affidavit? My passport and marriage certificate all have my new surname.

Good day house, I have my interview today and all went well, I was given a white pamphlet for my right in US and also was given another form to submit my Waec certificate and my wife recent tax transcripts... Now my first question is

1. Does the white pamphlet means visa is issued

2 the CO told me to submit my international passport along with my wife tax return and waec certificate but he never tick it on the form for me to submit my international passport. He only tick the other two documents but he said I should submit my international passport along with it.

3 with different stories have heard on visajoutney DHL won't collect my international passport if it's not ticked on the form.how are they going to issue my visa if DHL won't collect my passport. Thanks in advance as you reply

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.
