University of Southern Maine provides aids at an average of 14808 per student meeting 83% of students need. 100% of students with need receive financial aid at an average of 10474 need-based grant. They also provide other scholarships including Blackwood Family Scholarship and Community Banks of Androscoggin Country Scholarship.

Yeah, I agree with the previous answer. Try searching for sponsorships in your country as well. The university provides merit based scholarships too but I am not sure if international students are eligible for them. Better look their profile in OYA School or search in their website or maybe ask them.
