Mr. Mai,
Hope you have been well. It has been already over a year since i got my green card. You remember me, right? I sometimes feel unreal that I went through the application process and finished it with a positive result. Without your help, it would have been much more difficult and more stressful. I again appreciate your sincere help. Wish you and your family a happy new year.
Best,
Client
