If you want to go to Dubai for a job, first check if there are requirements for your talents and skills. You can Google-search about the right job opportunities for you. It is better to consider the right job match for whatever education, work experiences, talents, and skills you got.
Then have a self-evaluation. Are you mentally, emotionally, physically, and spiritually prepared to go to your target destination? Dubai is like a magnet that attracts many people from 200+ countries, thus, it serves as a strategic converging point for many nationalities, so expect the diversities. You must be flexible and must have that high degree of tolerance to co-exist and co-live with others.
Write your curriculum vitae (CV) in a very professional way. Update your LinkedIn profile. You can also have your profile website up and running for recruiters to know more about you.
Check your local recruitment companies of good standing, if they have valid and legal manpower requisitions from Dubai, then you can pass your CV to them. If you qualify based on the standards of the local recruiter and requesting company in Dubai, the standard operating procedures will follow — medical tests, pre-deployment orientation, and others as required in your country, then you will be provided with the airline ticket to join the company in Dubai, that hires you. Your company also provides an accommodation or an accommodation allowance. Bring extra money to cover your expenses in a month, in case your company does not give cash allowances in advance.
Other applicants must submit their CVs online directly to Dubai-based companies posting their current job opportunities. Some companies have arrangements with certain recruiters in certain countries of their choice. They forward your CV to the local counterpart that does the rest to deploy you for gainful employment in Dubai.
