Jeannine R.

During our 30 year real estate careers, my wife and interacted with many attorneys.
When we met Marco Costa, approximately 4 years ago, we finally found an attorney who is reliable, knowledgeable and always ready to assist with competence in multiple facets of the law. For those who have assets or business in Italy, it is important to point out that Marco is habilitated as a lawyer both in the USA and Italy. A must, when navigating different set of legal issues is very difficult.

Augusto M.

I had the pleasure to get in touch the first time with Mr Marco Costa when I needed my working visa, and then to get the green card for the family. Our case was definitely complicated due to the overlap of multiple countries and different assignments. Mr Costa managed to find the way forward, and minimize our exposure to the complications of the US immigration law. I have no hesitation in recommending Mr Costa and West, Longenbaugh & Zickerman for the help and support, as well as their willingness to exceed the clients' expectations.
