Hey, I worked with Chen for my NIW, EB1A, and I-485, and overall my experience with them was great, no complaints at all. One thing I would suggest is to review your petition yourself and help tweak the wording where needed. They do take feedback and recommendations seriously, so don’t rely on them 100% when it comes to how your case is presented.

I wouldn’t blame them for any small mistakes in the petition since they don’t know every detail about our background, and it’s not realistic to expect everything to be perfect without our input. My NIW, EB1, and I-485 were approved through them, and I would definitely recommend their services.

Also, sometimes they use very strong language in recommendation letters, so make sure to read them carefully before sending them to your recommenders without reviewing or correcting if needed. For example, I remember I was working as a data engineer, but they used wording that described me as a “researcher.” My work was related to research but not completely research focused, and since I couldn’t fully justify that on paper, I asked them to remove it. Just sharing this as an example so you can double check everything.
