Hello Jerry:

I hope this email finds you well.

Just wanted to let you know that after waiting for 100 days, I finally received my green card yesterday. Overall, the application went smoothly. Thank you very much for all your kind help with my application. I greatly appreciate it. As always, I'll continue to recommend your firm to my friends and colleagues in the future.

Again, thanks a million for all your help and time.

Sincerely,

Client
