Yes, it is possible for you to pursue Mexican citizenship under certain conditions. According to Mexican law, individuals with Mexican grandparents may be eligible for citizenship through jus sanguinis (right of blood). If your grandparent was born in Mexico, you could potentially claim Mexican citizenship, even if your parents are not Mexican. However, the process would typically require you to provide proof of your grandparent’s Mexican nationality, along with other documentation, and it may be necessary to go through a formal naturalization process.
