I am writing this mail today (Despite I am a bit late) to thank you for all your precious help in my immigration process.
I really appreciate the devotion to helping me reach my goal and fulfill my dream.
Despite my unawareness in the process, you were there as a guide to help me understand all the steps of immigration clearly.
I also appreciate the quick response from you whenever I needed information.
Thank you again for all your support and encouragement. It was a great pleasure to have you as my guide until the completion of my immigration process.
