The length of time you spend studying abroad will depend on the program and level of degree you’re undertaking. Generally, an undergraduate degree will take three or four years of full-time study (for example, in the UK the typical length for most subjects or courses is three years, while in the US the norm is four), while a graduate degree such as a master’s degree or equivalent will take one or two years. A doctoral (PhD) program will usually take three to four years.
At many universities across the world, there is also the option of studying abroad for a shorter period of time. Student exchange programs allow you to study abroad for a year, a semester or even just a few weeks. Information about these shorter programs should be available on the website of the main university you plan to enroll at, as well as the university you’d like to be hosted by.
