Every year a large number of students both international and domestic get enrolled for PhD and other doctoral research degrees. These are basically allocated on the basis of academic merit. They provide funding for up to 3 years or in may be more in some cases. In some cases 6 month extension is also available on application. If you are an international student, it may seem difficult to find a PhD scholarship but you’d be surprised that there are a significant number of PhD scholarships for international students out there. Most PhD funding from universities comes in the form of teaching assignments or involves carrying out research. Some foreign governments and institution also fund PhD degrees too.
