As an immigration consultant, how can I get what I want from my guests?

You need to know what he really thinks, what he wants most from the process of immigration, how much money and energy he is willing to pay for it, and know his real background in the communication with the guests (especially for the guests who invest in immigration).

Communicate with guests more and talk about some topics. This is not a question that can be answered clearly in one or two sentences. I can only talk about my own experience.
