Because she was 1 year old at the time of DV lottery 2015 application. Moreover, I want her to further learn my original language and culture. In case that my daughter is not entitled to register on Form-DS 260, how will I be able to bring her to USA in the future ? any advice?
Basically you have made a horrible mess. If you submit your 260 with her on, you will be disqualified. If you submit the form without her on they may discover the lie anyway (and deny you and probably ban you from the US). If you do make it through the DV process without her on the form you can never bring her in to the USA as your daughter because they will then have the proof that you lied on your original immigration forms. They would most likely revoke your Green Card at that point. If you wait until you have citizenship (5 years), you might be able to get through the process - but again - it is VERY risky.
My advice? Save your entry fees, forget the DV win and learn the lesson to always answer correctly. Brutal advice - but that is my honest opinion.
