You may or may not be a citizen. There are several criteria that must be met to acquire citizenship through a parent. There is not enough information about your immigration history to make a determination. A good starting point would be requesting a copy of both you and your mother's immigration files. This can be done by filing Form G-693 with USCIS. You can read more about citizenship at http://myattorneyusa.com/citizenship-and-naturalization.
