Evelyn Hahn is a compassionate immigration attorney and an Of Counsel attorney at David Hirson & Partners, LLP, which represents both corporate and individual clients from over 30 different countries. 

Her passion in immigration law deeply ingrained in her because she was one of them and personally underwent the same immigration process. Having a full understanding of the complex immigration process, 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. 

Evelyn, who primarily focuses on business and investment immigration, particularly enjoys working with companies, developers and projects that are creating social and economic benefits in the U.S. She has extensive experience representing small, mid-size and large Fortune 500 companies in IT, chemical, e-commerce, and other trade/business sectors, hospitals and other healthcare facilities, entertainment companies, and non-profit and religious organizations, all of which bring substantial benefit to the U.S. in different ways. She has filed over a thousand employment-based non-immigrant visas (E-2, H-1B, J-1, K-1, L-1, O-1, R-1, and TN) and immigrant visas (EB-1, PERM based EB-2/EB-3, and NIW) to date. She frequently advises her corporate clients about the immigration consequences of location change, mergers, acquisitions, corporate restructuring, employer sanctions, and immigration law audits including labor condition applications and I-9 verification. 

On the EB-5 side, Evelyn is uniquely positioned as one of the few attorneys, who represents both individual EB-5 investors and regional centers/project developers on all aspects of the EB-5 investment visa program, while having an in-depth knowledge of all types of business immigration. For her EB-5 project clients, she works with business plan writers, economists, and securities attorneys to design and structure EB-5 corporate and financing models, creates a new EB-5 project template, and advises on regional center creation and operations in compliance with EB-5 program. She also advises her corporate/developer clients on the complex issues of redeployment, potential and actual material changes and its related impact on the investors, and EB-5 immigration consequences of a failed project. 

Because she is experienced in project side of EB-5, she is able to view her EB-5 investor clients’ cases with different lenses than other attorneys who primarily represent EB-5 investors only. For example, she is not only able to advise on EB-5 investor’s source and path of fund strategies and prepare I-526’s and I-829’s, but also provide a full analysis of both positive and negative implications of any changes in the ongoing EB-5 project/EB-5 policy and its direct impact on the EB-5 investors. Because of her extensive experience in business immigration, she is able to design and formulate unique strategies for her clients, who are interested in converting from a non-immigrant visa status (i.e. E-2, H-1B, J-1, L-1, etc.) to an EB-5 immigrant visa status and advises on other complex issues, such as aging out children and visa retrogression.  

Evelyn has a particular passion in dealing with problematic cases with some of the most challenging and complex issues and is often referred to and recognized as the “best immigration strategist” by her clients for successfully resolving the issues raised. She has a great track record of using her own creative and unique strategy to successfully refile and obtain approvals on several denied cases, including L-1As, E-2s and EB-1A/NIWs, which were previously filed by different law firms. 

When the travel bans were first issued by the Trump administration in March 2020 due to the COVID-19 pandemic, Evelyn was one of the first few U.S. immigration attorneys, who immediately filed and successfully obtained approval on a request for an emergency visa appointment for her client using the national interest argument in early April 2020. She thereafter successfully obtained several other national interest exemption and emergency appointment approvals for her clients in the face of subsequent COVID-19 related travel bans. 

Evelyn also has significant immigration litigation experience in federal court, filing mandamus actions for unreasonably delayed immigration cases and complaints to challenge denied cases under the Administrative Procedure Act. She has successfully secured temporary restraining orders and preliminary injunctions for her client, who was able to continue to stay and work in the U.S. for the pendency of the federal litigation, which eventually led to an amicable settlement and a final approval of the case. 

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 and leads the firm’s Korean practice group, while managing the entire firm.
