Hi. I am currently doing my politics bachelors in Europe. The thing is, the program lasts 3 years, unlike the US bachelors that are 4 years in length. I was wondering whether it is possible to get admitted to a US PhD in polisci with just a 3-year bachelors. Most programs state that it is necessary to have a bachelors degree OR an equivalent degree from a foreign university. Do you have any insights on whether it is possible to do so, or even better, if you have been admitted to a PhD in the US with just a 3-year bachelors (but good overall profile). Thanks!!
