Dear Jerry,

It has been quite a journey over the past two years, from perm to adjustment of status. Today, my permanent residence application was approved. This email note is to express my gratitude towards your firm for representing me through the process. Especially XXXX for drafting a stellar petition letter, and always being prompt throughout the process. 

I would like to thank Kristin Whitaker for help with the recommendation letters, and very importantly encouraging me to apply in the EB-1A category. If you could share her contact information, I would like to send a thank you note. 

I highly appreciate your firm's expertise; you can count on me for referrals.

Thank you,
