- Contact your government
If there's no Dubai embassy in Manila or elsewhere in your South East Asian island, simply write to your government asking for the information you need, or other contact information (in other words, a referral to someone who knows). It's very important to get things organized long before you plan to fly to Dubai.
Whether you are traveling for school, business, or pleasure, you must be certain you've crossed all of your "T's" and dotted all of your "I's". It's vital to do some research and legwork before you prepare a passport and visa application for a trip. Your local passport office has likely seen and heard it all - they've fielded countless questions about traveling to other nations, so they are excellent people to contact regarding this sort of scenario.
It's entirely possible that you can get the forms you need right from your government, or from the passport office. A few emails or phone calls, made from the comfort of your home, can shed a lot of light on matters.
To locate embassies, passport offices, and government institutions related to international travel and affairs, do Google searches for your city name, plus keyword terms such as "Travel visa office" or "Dubai embassy".
