Hello Mr. Jerry Zhang, 

This is XXXX in Boulder, Colorado.  A few days ago, I got your card celebrating my birthday.  Thank you Jerry.  In addition to that card, this morning I got the photocopy of the receipt for filing my I-140 from your office staff.  I hope that everything is going well, especially the I-140 evaluation process.

During the period of cooperating with Mr. Alex Park for drafting recommendation letters, listing documents, and reviewing petition letter, I was very impressed with your staff's efforts to provide best legal services as well as the quality of services.  Furthermore, I recognized your staff's step-forward-processes to effectively motivate clients.

Thanks to Alex Park's endless efforts for high-quality legal services and your leadership management, I successfully finished drafting letters, collecting evidences, and filing I-140.  Thank you Alex.  Thank you Jerry.

I hope that you are doing well in your legal business as well as everything.  I look forward to hearing good news from the USCIS. 

Have a nice day. 

Regards

Client
