I have a fiancee in Japan.I am a US citizen. She has a 9 yr old daughter.when we get married and her and her daughter move to the USA. question my fiancee ask me concerning her 9 yr old daughter. Miho (her daughter) born in japan. My fiancee question is . Can Miho when she turns 18 (lets say) go back to japan if she decided she wanted to live there. Would she have to apply for citizenship again, etc: another question, are you familiar with the child laws, what should i be asking her so Miho can come here. Any special paperwork from the divorce or father. I know here in the states if full custody is granted to one parent than that parent can make the decision. Not sure when it comes to international custody.

She needs to prove that she has the fathers consent to bring the child to the us, either with a letter from the father or papers that shows sole custody.

Will she give up her Japanese citizenship? If not she would be able to move back whenever. See if Japan is good with dual citizenships.

did a little research and i found this:

A Japanese national is assumed to have renounced their nationality upon naturalization in any foreign country.

Under the revisions made to the Nationality Law in 1985, Articles 14 and 15 require any person who holds multiple citizenship to make a "declaration of choice" between the ages of twenty and twenty-two, in which they choose to renounce either their Japanese nationality or their foreign citizenship(s). Failure to do so entitles the Minister of Justice to demand a declaration of choice at any time. If the required declaration is not made within one month, their Japanese nationality is automatically revoked. A renunciation of foreign citizenship made before Japanese officials may be considered by a foreign state as having no legal effect as is the case with, for example, United States citizenship
