Dear Victor,

I was very pleased with your professional services with respect to my NIW petition followed by filing for adjustment of our status as permanent residents.  Both of us, me and my wife,  have received our permanent resident cards recently and wanted to share the scanned copies of those cards for your file, or for any future references, just in case.

I would be privileged to share our successful stories to any of your potential clients; if that is something I can give back to your professional practice.  Initially, I was hesitant to trust someone who I never had a chance to meet with in face-to-face.  However, your matured and experienced way of handling of my case quickly erased my skepticism. Finally, we are more than just satisfied from your very reliable, trustworthy, and competent services.  We wanted to say thank you to you and your team.

With best regards,

Client
