I am in Tokyo and I am a US citizen. I would like to become a member of the online marriage agency Pairs Engage, but they require uploading a 独身証明書, i.e. proof that one is single. Since I am a US citizen, they said that I need to obtain it from the US Embassy. I checked the homepage of the US Embassy and tried to figure out what I need to bring to the appointment I made. There is a form to download (here https://japan2.usembassy.gov/pdfs/wwwf7114.pdf). I guess I need to fill this out, but the form seems to be for people already knowing who to get married to, whereas I just need something to prove that I am single. Do I simply fill half the blanks?
Does anyone have experience getting a proof of single status from the US Embassy and can inform me of precisely what I need to do? Also, how long will it take for me to receive the certificate? On the same day of my appointment?
