ZLG is a boutique law firm that specializes in guiding companies  and individuals through complex immigration terrain - advising on all aspects of U.S. immigration law from visitor visas through naturalization. The firm also offers advisory services to assist with immigration program design and function including employer compliance.



The Ziegenfuss Law Group PLLC (ZLG) was founded fundamentally to help people and make an inhuman process survivable for those that go through it.  The only way I know how to make something as challenging as US immigration better is to thoughtfully provide the most expert and creative legal strategies and the highest levels of service.  I view each client relationship as just that - a relationship - and making those relationships thrive by building trust helping these individuals get to where they need to be means the world to me.

I have provided legal services to industry-leading multinational companies across a broad spectrum of industries including law, consulting, financial services, technology, pharmaceuticals, sports, and entertainment as well as directly to individuals from newly arriving asylees to UHNW individuals.  I understand the needs clients face whether that client is an individual planning a new life in the U.S. or a large corporation where global mobility is essential to their business model.  

The bottomline is that when immigration is involved, it is always critical and someone's future is in my hands and I practice immigration law accordingly.  Each client must receive the best that I have to give and must feel that they had an advocate who, regardless of outcome, found the best path forward for them.  Through all my years of experience and helping so many achieve their goals, this is the only way I have seen to ensure that those outcomes are overwhelmingly positive.
