Dear Mr. Zhang,

I would like to let you know that it has been a pleasure to work with Linda Gong, your assistant.

I worked with her on two H-1B cases for me and my husband, and we just successfully submitted PERM application to the Department of Labor. Linda has been very efficient, handled all matters very professionally, responded to all questions promptly, and provided valuable advice.

She has been providing excellent service, and I hope that you will take this into account during her performance review at your firm.

I look forward to continuing working with your firm on my case and I will definitely recommend Zhang & Associates to my colleagues and friends.

Sincerely,

Client
