I’ve never gotten an RFE. This is my first time submitting and I’m using a joint sponsor as well. I made sure to submit my W2s and my joint sponsors W2s and I know my joint sponsor makes WELL over the minimum amount needed. I’m also in a WhatsApp group of people petitioning their spouses from the same country as me so we are always sharing information and checking if we have any questions or anything. So I’m really praying all goes well. I know with people in our group that had an expedite they got their interviews scheduled within a month so maybe you will be the same🙏🏻
