The first screen owes an answer about Illinois, not a hero photo of downtown
The top of the page should tell a reader what kind of cases you take and where you can act, before it tells them anything about your building.
Two facts belong above everything else: the case types you handle and the states you are admitted in. A person holding a notice wants to know if they are on the right site. Photography, taglines and a slider full of stock imagery answer neither question.
Coverage matters more here than in a single state metro. Immigration work is federal, so you can generally act for clients wherever they live, but readers do not know that and will assume the ordinary rule about lawyers and state lines. One clear sentence resolves it and keeps the Metro East reader from bouncing.
Keep the language plain enough for someone reading in a second language. Short lines. Concrete nouns. The case type named the way a client would say it, with the formal term alongside if you need it.
Then the phone number, large, tappable, and next to the hours it is actually answered.
