Success of Legacy

Causey & Ye Law is proud to represent people from all over the world. At Causey & Ye Law, our bilingual attorneys provide every single client with exceptional legal service without borders.   


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 practices in various areas, including Criminal Defense and Civil Litigation in Iowa, Immigration Law nationwide, and International Business matters between the United States and China, including legal 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, Iowa City, and Dubuque, across the United States, dealing with immigration matters in Iowa, California, Illinois, Mississippi, New York, Tennessee, Texas, Virginia, and Washington D.C., and has served many international clients from China, from areas such as Beijing, Hong Kong, Shanghai, and Shenzhen.  


Causey & Ye Law always has its eye on the core value of the firm: Diversity. Causey and Ye Law, unlike many other immigration firms, represents its clients throughout, no matter the legal challenges. Causey & Ye Law is devoted to providing the best customer service, and that means offering a “complete package” of legal services. Immigration cases are complex, and they often lead to issues in other areas of law, such as criminal defense, family law, and business law. Causey and Ye Law will deal with those issues as they arise, and it will 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 beginnings. The firm has satellite branches in both Ames, IA and Iowa City, IA, which allows it to assist the international students and nearby communities.
