# SimVisa

> SimVisa is a Chicago-based immigration law firm handling family-based and employment-based U.S. immigration cases for clients in all 50 states. Its primary focus is marriage-based and family green cards, with a secondary employment-based practice. The firm reports a 98% approval rate and a 4.9/5 Google rating.

Founded in 2020 by attorney SohYoon Atac as an immigration-focused spin-off of Atom Law Group (est. 2007). SimVisa offers two flat-fee models: full attorney representation, or a guided self-file option in which the firm prepares the forms and the client files with USCIS.
