About Us


 Causey & Ye Law’s vision is to be the preeminent law firm in Iowa with regards to Criminal Defense, to be recognized nationally for its Immigration Services, and to guide International Business Development and Investment in the United States and abroad. In achieving its goals, Causey & Ye Law promises never to take on matters that cause it to sacrifice the integrity of the firm or its clients.

Causey & Ye Law offers a variety of service areas, including Criminal Defense in Iowa, Immigration Law nationwide, and International Business matters between the United States and China, including matters involving a United States based business with foreign investors. Causey & Ye Law 
has served clients throughout Iowa, in cities such as Des Moines, Ames, Ankeny, Cedar Falls, and Dubuque; across the United States, dealing with immigration matters in Iowa, California, Illinois, Mississippi, New York, Tennessee, Texas, Virginia, and Washington D.C.; as well as international clients in China, including the areas of Beijing, Hong Kong, Shanghai, and Shenzhen.

Causey & Ye Law keeps its focus on the core value of the firm: Diversity. Causey and Ye Law, unlike many other immigration firms, stays with clients no matter the subject matter. Causey & Ye Law is devoted to providing better customer service, and that means offering a “complete package” of legal services. Immigration cases are 
complex and often lead to issues in other areas of law, such as criminal defense, family law, and business law issues. Causey and Ye Law will deal with those issues as they arise, and assist you in seeing your case through to completion.

As a part of providing better customer service, Causey & Ye Law has branched out beyond their Des Moines, IA office. The firm has a satellite branch in Ames, IA, which allows them to assist international students who attend Iowa State University 
with any legal issues that arise.
