Doubt of being given the Visa.

Prince, sorry to hear that, but it is the case. No one can assure that your application will be granted after you submit the round trip air tickets. But the round trip air tickets are necessary for the application.
If you don’t want to provide the round trip air tickets, you can book a tour from a travel agency and then ask the travel agency to get an invitation letter for you. In this case, the air tickets may not be required anymore.

Thanks so much. But when they asked me to bring the ticket I went to bring then a booked ticket and they said they need an original ticket and a paid one. So I think that is what is needed before I will. Be given the Visa. But can someone pls help me as to why they need a plane ticket before I am given the Visa but all the others who came where given their Visa's. I don't know but I think it's because of the Visit. They want to know they intended date of travel and the intended date of return in specific so that I dont over stay there.

Yes, your understanding is exactly correct. They just want to make sure that you won't overstay.
