Startup Overseas Forums

Hi, I wanted to know if any license/permission is required to be taken to host a small investor meet in Dubai. My company is into real estate sales, and we represent quite a few developers in India. The event will be held in a banquet hall of a hotel and interested investors will be invited to have a one on one discussion with us. They will be invited through a high blitz marketing campaign through the internet. Awaiting to hear from you. Regards Vinay
