Is your mother married or single? Was she ever married?

What is her country of birth? etc.

Are you and your mother waiting for visas abroad OR you are already in USA (illegally, overstayed, or on some visa)?

Is your grandmother a USA citizen? Was she a USA citizen when she applied for your mother?

As you can see, you didn't provide enough information in order to advise you. You should consult an immigartion attorney for advice (not a "notario").

If you’d like to schedule a telephone or email legal consultation, or need advice or help, please let me know, and I’d be glad to help you: Attorney [@] law-visa-usa.com

All of this will depend on what category of visa your grandmother sought. Questions such as whether your grandmother is a U.S. citizen, or became one during the process, are important to know to answer the question. As well, whether you were married or now are, are some of the questions. To provide you an answer, we'll need to view all of immigration forms which were filed, the fee receipts, your passport, and more.

If you would like to schedule (or if you family would like to schedule) an appointment at our offices in Miami, FL, please let me know.

Sincerely,
