Dear Dr Bush and Dr Zhang,

I am very glad that with your persistent assistance, my I-485 was finally got approved. It was certainly late considering that my wife's green card arrived almost 4 years ago.  However, this unusual experience created more chance for me to know you and your firm. By far, you are the best team in US for immigration.

Again, I want to thank you very much & hope you have a great day !!

Sincerely,

Client
