Charging a sponsorship fee to a foreigner

I am working as a business sgent in UAE. As per law of UAE, any non-national investor must do a business agreement with a UAE nationality holder to set up any personal business in the UAE. For this business agreement, the UAE nationality holder charges an amount to the non-national investor and that amount is known as the sponsorship fee. As a business consultant, I settle the business agreement between the foreign investor and UAE national. For doing this service, the UAE nationality holder gives me a commission from his sponsor fee. Please advise me if this commission is halal or haram according to the ruling of Islam.
