Ok so I checked on the website and his K3 approval for USCIS was on Sept 12. Now how long does it usually take for him to get everything done and get an interview. I was looking on a lot of people's timelines and it seems like the norm is like 2 or 2 1/2 months. So what do you need to bring and how hard is the interview. Does anyone know if they are being harder on the men than the women?
