Hi. I'm not sure what to put in the current legal name field of the n-400. In Brazil the mother's maiden name can be considered a middle name or first last name. On my birth certificate the name is just written on one line, with nothing saying what the middle name is and what the last name is. Previously Brazilian passports put the mother's maiden name in the first names field, but then they changed it to be in the last names field. Consequently, on my Brazilian passport, my last name is listed with two words: first my mother's maiden name, which I consider to be my middle name, and then what I consider to be my last name. I had thought I would just ask for a name change in my n-400 but that is not an option at my field office apparently.
Here is an example of what is going on:
Birth certificate: Name: John Jacob Smith
Brazilian passport: First name(s): John; Last name(s): Jacob Smith
Green Card (they had to go by name as written on passport): Surname: Jacob Smith; Given name: John
What I would like on my US passport/future documents in US: First name: John; Middle name: Jacob; Last name: Smith
On the n-400, does it make sense to write my current legal name as First name: John; Middle name: Jacob; Last name(s): Smith? Obviously I would then also write Surname: Jacob Smith; Given name: John in the field about writing my name exactly as it appears on my Green Card. I am trying to avoid having to go through an annoying and expensive name changing process after getting my citizenship since I consider this to be one way of writing my legal name in my home country.
My top priority is to not cause delays and get my citizenship as soon as possible. I am pretty sure everyone here will just advise me to write my current legal name as it is on my Green Card, which is what I have used as my legal name in the US, and which is also considered my legal name in Brazil (even though Brazil would *also* consider the version with Jacob as my middle name to be my legal name). I'm sure it is safe to write my current legal name as it is written on my passport/Green Card since that also matches my birth certificate, but it is so annoying to have to go by this hard-to-pronounce two-word last name. Maybe another Brazilian has gone through something similar. I think most people will say it is safest to just change my name after naturalization in order to avoid delays, but let's see.
Thank you for your thoughts on this!
