Hi Jerry,
My name is XXXX. I'm a previous client of your firm. Mr. Gabe Griesbaum had helped me on my EB-1B case, and I received my I-140 approval on 2015/04/07. I would like to express my sincerely appreciation to Mr. Gabe and your firm for your excellent work on my EB-1B case.
Thanks so much for your help.
Best Regards,
Client
