I hired Emily while she was working at Challa Law to file my permanent residency application under EB-1A category. She worked with me patiently through various stages of the process. She helped and guided me through every step, from writing reference letters to responding to USCIS queries. My I-140 application received a lengthy request for further evidence notice. Emily helped me obtain the necessary additional documents and also drafted an excellent cover letter to address various issues raised in the RFE. This resulted in a quick approval of the I-140. I strongly recommend her services for filing immigration applications.
