Hello Mr Le.

I wish to acknowledge receipt of the Approval Letter (ImmiVietnamVisa) that you kindly sent to me today. May I take this opportunity to thank you for the way that you have handled this matter and also the most speedy and efficient service that you have personally provided. Thank you also for the advice on what to do next in the process, and I am sure that both my wife and I will enjoy our visit to your country.

Kindest Regards.
