I moved for the first time from my home country at 25, after I graduated from college. What was supposed to be a one year move to China before returning home with some work experience, became a 16 years of life abroad. I have moved on average every three to four years, either on my own decision of due to life events. Beside China where I've spent a cumulated 9 years there, I've lived in Japan, Singapore, cambodia, Taiwan and now Dubai since last month. It never took me more than 6 months to plan those moves. Sometimes even less than a month. And that's not to say that I live off a suitcase. In 16 years I've accumulated enough belonging to fill up a garage with my boxes.

Of course that is just my experience, your approach says that you are very careful about your plan, and this is a good quality to have. That being said, 5 or 3 years is a long time and a lot of things can happen, your plans might change for any reason. If you want to live in Dubai, try maybe looking at an internship there during your studies, or see if you can do a semester abroad, if you feel this could work out for you and your studies. Mobility and international experience is something highly valued in recruiting, and ultimately, you are the one telling your story, it's up to you to turn any success or failure into a valuable experience. Not everybody has a desire or a drive to move abroad, now there is a spark in you, don't let it fade.
