Clarissa M. Kalil

Immigration Attorney

Clarissa M. Kalil, Esq. has dedicated her life to helping immigrants navigate the immigration process. Kalil is a dual licensed attorney in two countries: Brazil (OAB/GO 35665) and in the United States (Missouri Bar 71440). Her practice is exclusively dedicated to the U.S. immigration law. Since her office only handles immigration matters which is federal law, she can represent clients in all 50 states in the U.S. Immigration law is federal law enforced by a federal agency. As such, an immigration attorney admitted to practice law in any state can represent a client before DHS, USCIS, the BIA, or any immigration court in any other state.

Having witnessed her own parent’s journey to obtain a green card, she is determined to help as many families as possible. Born in the United States, Kalil and her immigrant parents moved back to Brazil when she was four years old. Kalil is the third-generation attorney on her father’s side. Growing up, she was passionate about justice for as long as she can remember. I dreamed of living in a world that provided equal opportunities for everyone”, says Kalil. At just 16, Kalil enrolled in law school in Brazil, as the youngest student in her university. She spent 5 years studying and obtaining her degree before spending the next 3 years working as an attorney at a full-service law firm, handling civil, labor, and family law matters.

Her inspiration for justice came from her own background. During her time in law school, Kalil suffered a horrible mistake at the hands of a pharmacy that gave her the wrong medication. She was given medicine containing a double dosage of corticosteroids which caused suppression of her immune system. She ended up in the hospital with sepsis and Acute Respiratory Distress Syndrome (ARDS). She entered a coma and for several weeks, her failing lungs were kept alive through machines. This experience only strengthened Kalil’s drive for justice and after making a miraculous recovery, she resolved to fulfill her dream of moving back to the United States. A few years later, Kalil returned to the United States as she was determined to obtain her US law degree.

While attending the Northeastern University School of Law, Kalil spent time volunteering at non-profit organizations, working in immigration clinics, and focused her studies on Immigration law, International Human Rights, and asylum. In 2019, she passed the US bar exam and founded The Law Offices of Clarissa M. Kalil, PLLC. Clarissa Kalil’s immigration law services include family-based green cards, humanitarian-based forms of relief, and some employment-based green cards. Unlike many other immigration law firms, Kalil’s firm explores a variety of immigration relief options. It’s never a one-size-fits-all solution,” says Kalil, “We do our best to help our clients achieve their dream of success in the U.S.” The philosophy of the Law Offices of Clarissa M. Kalil, PLLC is simple: “We evince our commitment to each client by providing a class of legal service that is peerless. I feel very grateful to collaborate with and become part of the American Dream of other people. This is the driving force for me to help and do my best to help all of our clients to obtain their right to live and work in the United States without fear.”
