Dear Deekshith: Since your brother is already a resident of Dubai, I would strongly encourage you to obtain a visit visa and apply to employers while you are already there. Your brother can act as a sponsor and sponsor you for a visit visa.
However, before you head out, I would advise you to do your homework from your home country. You can start by networking with other professionals who are looking for work in Dubai. You can usually find lots of forums online or even start speaking with friends of family members about your goals. See if you can get information on upcoming companies or already established companies in Dubai. You can even start making phone calls from your home country to see if you can get through to the HR officer and establish a rapport. Once you have created a heavy contact list, you can plan your trip.
Bear in mind that Dubai is a luxurious city so it’s easy to get distracted with the sights and nightlife. Basically, you have to keep strong with your job search. It’s never easy to find work in a new place. However, with some persistence and a little bit of hard work, I’m sure things will look up.
Don’t stop your network once you are in the city. Start working on your social skills to create your own circle of friends and acquaintances, as you never know where your ideal opportunity will come from!
Research by Career Management Consultants suggests that networking increases your chances of getting hired by 30%. You can build that network while you are in Dubai as well. Try a few places from this list and you might find a little luck in your job hunt : Irish Village, QD's, Rock Bottom Café, Zinc, Barasti Bar, Aussie Legends, Go West (Ironic), Dubai Marine, Jumeirah Beach, Jimy Dix, Uptown, Trader Vic's, Koubba, Century Village, The Alamo, Fabber Magee's, Boardwalk, Studio One, Scarlett's, and Spike Bar.
