Hi,
If your profession in your ID is Engineer you and your family will get visa on arrival in Dubai for 14 days and the charges has been increased to Dhs. 300/-. There is a form to be filled and it will be better if you can manage to get them before going. You should go to the eye test with the filled form and after that you go through the escalator to the immigration and before going to the counter purchase the electronic cards (fee for the visa - a must). You will get the visa stamped on the Passport and copy of the filled form (yellow one) will be given back to you which you should keep with you to show in the immigration (a must) while coming back.
