Adriana Guadana-Huizar

Adriana graduated college in May of 2021 as a first-generation student. A proud daughter of two Mexican immigrants, she earned her Bachelor of Arts in International Studies and Anthropology. Adriana interned with the Chan Law Firm in 2019, and upon graduation joined the team.

Her passion for immigration came from her family’s personal challenges within the immigration system. She vividly remembers the long, systemic hurdles of filling out immigration paperwork: particularly the language barriers, economic challenges, and sheer lack of understanding of the process.

She hopes to one day become an immigration attorney and help families like hers be able to understand and obtain immigration relief. She keeps the stories shared with her close to her heart, and fully believes it is these stories that are her drive and fuel to continue to advocate.
