Hi,
So I (US citizen) have been divorced for over one year. My child's (half-jpn)birth was not registered at the us embassy. My situation is complicated as is, but short answer, NO i do not see them anymore.

If my kid needs a US passport at some point in the far future:
What would I need to prepare for them?
I checked the embassy website and because of dual-nationality they would need some forms to prove relation to me.
If my kid doesnt get a passport would they still be able to enter Japan like a regular Japanese national or is this not allowed?

it sounds like if he doesnt get one he can never come to the states... I hope thats not the case.
