Unfortunately not until they turn 21 and can file a petition for you. Also if you are in the United States, then we need to know how you entered. Was it through a visa or crossing the border?
If a visa, at this point in time, once they turn 21, they can petition for you. If you entered without inspection (cross the border) then, unless you benefit from INA245(i), you will not get this chance. Nonetheless, if you are placed in removal proceeding, the kids can be one element to get you a cancellation, but you need to meet the other thresholds. Therefore, the answer is not so simple.
Good Luck to you
