Since I am in Nepal, I thought I should try to obtain the NRN Citizen, but looks like I am sort of a document. When going through the process, I found out that I need both US passport and US Citizenship certificate. I just brought my US passport but I do not have my citizenship with me. From what I see US passport should be enough but looks like they need both. I see people with British passport are good with just a passport only. Can people share their experiences and problems that they encountered when going through the process. And also if they were able to solve these problems as well.
