Akiko Yamada, Esq.

Akiko Yamada, a founder of Tigris Legal PLLC, is an attorney licensed in Japan and New York. Born and raised in Japan, she started her career as an attorney at a top-4 law firm located in Tokyo. There, she practiced general corporate and finance.

After practicing law for about 6 years in Japan, she came to New York to attend law school, and decided to pursue her career as an attorney in the U.S. Since then, she had worked at multiple litigation law firms based in New York, and gained extensive experiences in commercial, medical malpractice, and insurance litigation.

During the time in the U.S., she has also gained extensive knowledge and skills on the U.S. immigration practice. She underwent F-1 and H-1B non-immigrant visa proceedings, including visa lottery, application, extension, RFE (Request for Evidence), transfer, and recapture of unused time. In 2021, she filed an EB-2 (NIW) green card petition for her family in the STEM field and successfully obtained USCIS’ approval, through which she obtained a U.S. permanent resident status as well.

As an immigrant herself, these experiences strengthened her interest in U.S. immigration practice, which led her to found Tigris Legal PLLC. Since then, she has been devoting herself to supporting clients who seek to obtain U.S. nonimmigrant visas, employment-based/family-sponsored green cards, citizenship, and relevant U.S. immigration benefits. She finds the immigration practice very rewarding as she may assist clients in pursuing study, career, family unification, or a new life in the U.S., which are oftentimes critical life events.

Client Testimonials

“The attorney handled my NIW green card case with great efficiency and care. From drafting letters to helping me gathering the necessary documents I always received timely and accurate guidance. My case went perfectly smooth without RFE and I received my green card directly on the mail without interview. Would recommend this law firm to anyone.”


“I worked with other law firm for my Eb2 NIW, which was a little frustrating to me. So, I chose Tigris Legal for my consular processing. I would say I should have chosen Tigris for my I-140 application. Quick responses, hard work, adequate advice etc.”
