Success Stories: A Ph.D. Student from Germany Pursuing Brain and Cognitive Sciences Secured I-140 (NIW) Approval After Presenting a Personalized Petition

Everything went well and I’m glad I went with Chen Immigration Attorneys. I was deliberating doing it all by myself, but I’m glad I didn’t, since this was so much easier, and I felt assured throughout the process that everything was done to maximize my chances of securing approval. Communication was easy through the webtool and the instructional documents were clear. I’m also happy that the attorneys suggested to go with only one independent reference in my particular case, since getting references just adds extra time and is a hassle. All around happy with my experience.
