My wife had her IR1 interview in Lagos in March of 2024 and she received a 221g requesting a DNA test to determine paternity of our son. I'm not sure why, because he's already a US citizen with a US passport, but that's a different conversation. She finally just had the appointment to collect the DNA sample in Abuja. My question is... what do we do once we get the results? The paper says to make an appointment using AVITS to drop off documents and passport, but I just tried it and it told me the case number was invalid. Any help would be greatly appreciated... we first filed with USCIS in April of 2022 and consulate errors have been dragging out the process. We would be so frustrated if she gets her visa right after the new president institutes a travel ban... then we would have to wait another four years just to start the whole process over again. Our son is now three and is growing up without his father. Thank you.
