You can get citizenship by applying for it, not because your mother is a US citizen but because you have been a permanent resident since you were 16. All you have to do is apply for US citizenship, pay the filing fees, pass the interview and then be sworn in. Please let me know if you have any additional questions or how I can be of further assistance to you in this matter.
