I agree with my colleagues. Depending on a couple factors, you might be a citizen already. Bring all the paperwork/information about your entry into the U.S. and your mother's citizenship to an immigration attorney. You can see if you are already a a citizen, or if not, what your other options are. Good luck!
You may or may not have derived citizenship from your mother, you need to consult with an Immigration Attorney as soon as possible in order to review your particular circumstances and determine if you meet the requirements for derived citizenship.
