US Immigration from Nigeria

I was scheduled for interview in July, but my wife couldn't find our marriage certificate(still searching for it though), can I go with a scanned copy? Hope it's acceptable? I need urgent responses to this. US-Embassy in Lagos, Nigeria.

What is to be done next if uscis approve form I-130? Is my husband going to send them his current account balance while doing the affidavit of support? Or is he only going to send them his annual salary

Please house, am from Nigeria and my husband is an American. We want to file for form i-130 and form i-130a online, but we don't know if it's best to do it ourselves or is it better to employ the services of an attorney? I would really appreciate if I get feedbacks.

Thank you.

Dear Family,

Can anyone advise who and when to file i-824.

Thank y'all.

Hello Visajourney family, I am asking for a friend who just received interview CR-1 letter in Nigeria who moved to new address, while the previous family address has not been changed at NVC.

Will a physical letter be sent to the previous address? Or what is current procedure? I heard that B1 interview letters are all digital, but this is a CR-1.

If so, what is best way to notify and make sure the new address is used.

Thank you in advance.
