“I had an amazing experience with Manifest Law from the first intake interview, through a fast and professional process of working on the file, to a straightforward approval of my case. Catlea Bobis is a superstar attorney, and I recommend everyone considering trusting your case to professional support like I had with Catlea and the entire team at Manifest Law.”
Irina Batukhtina
“I have worked with Dan and Simon directly, and my experience has been like no other. It feels like I'm talking with actual people who care about my case. Any questions I had, they were happy to assist me with in a very short time and make sure everything was clear before moving on to the next thing. I will definitely be working with them again in the future.”
Sandra Rocha
“Exceptional service. Fair pricing, worth every dollar. Had a couple of consultations booked with Simon. Wasn’t trying to upsell or anything like that. Crystal clear info and guidelines, exactly what I was looking for.”
Daniil Sigal
“I was using Manifest Law’s services during my EB-2 NIW process. The Team was very professional and my petition was approved. I highly recommend their services.”
Andras Titton
“The team was simply fantastic. Initially, I thought my case was not highly strong. What impressed me most was their legal expertise extracting the most valuable insights from facts to support my case. Communications with them were effective and pleasant. I greatly appreciated the team's understanding and quick action. I would highly recommend them.”
