Thank you so much Kay for your great effort on helping us.  Both my partner and I are very grateful to your excellent service and hard working as well as your considerate thinking of us always.  Basically we did not need to worry about much on how to prepare the application, as you had carefully organised everything for us.  We both really appreciate your great work for us and we would like you to help us for the next stage visa application too.  Many thanks and take care.
