As stated to you on the other legal site where you posted the identical question, you cannot do this unless she goes to court and is awarded custody.
If she did this without a court order she could be arrested and sent to prison for criminal interference with custody.
You have three options in this situation:
1- you can file a petition for emancipation. If emancipated, you would be on your own and would have the right to live wherever you choose.
2- your biological sister can file for custody of you. This would require her showing a court that you are somehow deprived in your adoptive parents' custody; or that, for some other reason, custody needs to be removed from them.
3- you can wait it out until you turn 18, at which time you will no longer be considered a minor in the eyes of the law and would be free to live wherever you choose.
The above answer is a general explanation of legal rights and procedures. It does not constitute legal advice. Nor does it establish an attorney-client relationship between the individual posting the question and the attorney providing the answer.
