Hello. Doing your homework on a firm before booking is exactly the right instinct, especially for business and immigration work. You can read up on the background and approach in the About Liberum Law https://liberum.law/about-us/ section – it lays out who they are, their focus, and the practice areas they cover, which is a good way to size them up before a call. From what I know they’re full-service across eight areas and work with both individuals and businesses in Illinois and nationwide, so business and immigration together is no problem for them. Have a read, and if it lines up, book the consultation with your questions ready. Due diligence like this usually pays off.
