Good morning Mr. Zhang,
First of all, many thanks for sending the birthday greeting card.
We filed my I -140 application on last Friday. I would like to take this opportunity to convey thanks for assigning my case to Attorney Lynn Greening.
Lynn has done an extraordinary job from the start. She has given me excellent suggestions on recommendation letters, and the most impressive thing is that she is very punctual.
I am extremely happy to work with her, and I would be more than happy to refer her to all my friends who would be interested in applying for a GC in the future. I felt that she is the best and definitely deserve a great review regarding her work performance.
Once again many thanks for filing my case , and hope everything goes well.
Have a good day/week.
