So I'm gonna change my legal gender in... Like 3-4 years. Here in chile it's not necessary to have SRS, just HRT. I'm gonna go live in Japan as I turn 18. But I'm scared that as in Japan SRS is mandatory to change legal gender, I'll have to be female again to have Japanese nationality? Ahh I don't know, as my gender would be already male... IDK help?
Does Chile issue a new birth certificate with your new legal gender? If all of your identity documents/paperwork from Chile have your gender listed as male by the time you're applying for Japanese nationality, I can't imagine they would even know that your gender had been anything else!
