Mr. Kaye:

The oath ceremony went well. Thank you for putting up with all my timely and untimely telephone calls with patience. Like they say, you never lost your cool. I appreciate your promptness in processing my emails and providing timely feedback. It certainly was an arduous process and would have been difficult without your help. I know you are busy, yet you rarely let me know. Please thank all your excellent staff, who were prompt and courteous throughout the ordeal.
