Licensed travel agents and hotels in the UAE can arrange a tourist visa for you provided you purchase the ticket through them and maintain hotel reservation with the specific hotel.
You can also contact travel agencies in your country for any tourist packages available to the UAE in collaboration with a local tour operator.
It is important to check the authenticity of travel agents you are dealing with and refrain from paying or sending copies of your official documents until after you are 100 per cent sure the tour operator is genuine. You can seek the help of the UAE embassy in your country for verification.
Note: The UAE embassies do not issue tourist visas. In order to get a tourist visa to the UAE, you need to get in touch with one of the UAE-based airlines, a tour agency or a hotel (where you intend to stay) in the UAE who will apply for visa on your behalf to the official visa-issuing authorities in the UAE.
