Hello everyone! We managed to schedule an interview this May and we couldn't thank you all enough for the help! However, we have realized that our I-129F validity will expire days before the interview (There aren't enough slots for an interview and we needed to wait). We called the consulate in UAE to ask for an extension and they just said to contact USCIS/NVC for it. They said that all they could do in the consulate is to address inquiry and concerns about appointments. For people who did their interview in UAE, is this true or we just called the wrong person? Also, what is the best way to extend I-129F? Thank you in advance for all your help!
