Salaam AFGgirl and thank you very much for the information. After I posted this question, the embassy did contact us via email and setup an interview date for my fiancee. So, inshallah things will workout. I hope that your case has been resolved as well. Apparently, the U.S. embassy in Kabul has streamlined their process for K1 visa applications. The interview notice also includes medial examination and other required files and fees as well. Anyways, I wish you all the best and everyone who is waiting for their loved ones to be united.
Thanks,
