International Educational Consultant,
As mentioned in some of the other answers here, it is extremely hard for international students to get full scholarships for a Masters degree. U.S. universities regularly give full scholarships for a PhD degree, but not for a Masters. I would tend to agree that EducationUSA is a good resource for financial aid updates and I would encourage you to get in touch with an EducationUSA Advising Center to help you with the process. You can see a full list of the centers here: http://www.educationusa.info/Philippines . And if you have any schools in mind you should definitely get in touch with them to see what kind of financial support they offer (if any).
