text: my sister is trying to kidnap my little sister! help? my mom left the country over 6 months ago with plans to start a new life in france and to have my little sister brought over when she was stable.  she left my younger sister with my older sister. now my older sister is trying to obtain gaurdianship of my younger sister (now 14 yrs old) without my moms permission. can she do this?  p.s. - my mom cannot come back to the us due to her immigration status but my lil sister is a citizen. if she's looking to take custody, thereby taking away your mother's rights, she cannot. your mother does need an attorney tho. if she's looking for gaurdianship in terms of emerency contact, your mother still needs to set that up. your mother still needs an attorney. your sister would have to prove that your mother is a danger. since your mother cannot come back because of her status, she needs to contact the french government and talk to the us embassy there.
