Dear Mr. Zhang,
Greetings, I would like to take the opportunity to thank you and your office staff specially Mr. Mai for such an amazing job you did with regard to my NIW case. I would definitely continue to work with your office for my I-485 application and also will offer your law office to my friends and others to pursue their immigration goals. Once again I appreciate your guidance and support during the past few months.
All the best,
