Dear Yaping Zhan, 

Thanks very much for your email. 

I am writing to you to confirm that I received the I-140 Receipt Notice attached in your email.

I was very much impressed by the professional and efficient service provided by Attorney Wang and Mr. Sean Su. Their immdiate and precise replies to my enquiry, good wrting of the document, patient and professional guidance offered by them are very valuable  treasure for me to handle business affairs. I learnt much from them and I am very much indebted to them.

My sincere thanks also goes to any person who worked for my case in Zhang & Associates, P.C.!
