Evelyn Hahn is a compassionate immigration attorney and a Managing Partner at David Hirson & Partners, LLP.

Her passion in immigration law deeply ingrained in her because she was one of them and personally underwent the same immigration process herself. Having a full understanding of how difficult, challenging and complex the entire immigration process can be based on her personal experience, her goal is to help each of her clients, both corporate and individual clients, to expand into new opportunities, overcome obstacles, and ultimately achieve their immigration goals in the U.S. She truly believes in helping her corporate clients move around/hire talented foreign national employees to work on their critical projects in the U.S. as well as individual clients achieve their American Dream just like she did. 

She represents both corporate/business clients and individual clients on all aspects of immigration law, including business, investment, and family immigration as well as immigration litigation. 

Evelyn represents small, mid-size and large companies, both domestic and multinational companies, hospitals and other healthcare related facilities, entertainment companies, as well as non-profit and religious organizations and successfully filed hundreds of employment-based non-immigrant visas, including E-2, H-1B, J-1, K-1, L-1, O-1, R-1, and TN visas as well as immigrant visas, including PERM labor certifications, and EB-1 (EB-1-1, EB-1-2, and EB-1-3), EB-2 including the National Interest Waivers, EB-3, and EB-4 immigrant petitions. She also advises her corporate clients about the immigration consequences of mergers, acquisitions, corporate restructuring, employer sanctions, and immigration law audits including labor condition applications and I-9 verification.

She also focuses her practice on EB-5 investment immigration, representing both individual investors on I-526s and I-829s and regional centers and project developers on all aspects of the EB-5 program, including regional center creation, establishment of new EB-5 projects by filing the Form I-924s, and the EB-5 program compliance in general.

Evelyn also has significant litigation experience – not only in representing immigration clients in federal court but also representing clients in civil litigation in various types of legal matters, including business law, employment law, family law, personal injury and bankruptcy. 

Evelyn has spoken at several conferences, seminars, and other speaking engagements, covering various immigration topics. She is licensed to practice law in California and District of Columbia. She is fluent in English and Korean.
