As far as I can see, the only thing I can do right now is trying to get a name change to Noah, hoping it passes as a male name. I'll need to dress male for the request. If they catch me being transgender I'll be denied the request and force to wait two damn years. At least that way I wouldn't be forced to give explanations about why the name I'm using differs from the legal name.
I just need a copy of my birth certificate (online request), a census certificate, proof that people use that name in private communications, two witnesses....
And paying again for reissuing every ID card, driving license, credit cards, transport pass, etc... Ain't cheap and takes time. I just ordered the birth certificate and tomorrow will request the census one (hope the digital ID card works this time with the card reader)...
