Even some people suggested my to volunteer for some NGO works...

Please help me out... I really wanna study in US of A... & i want to really have a good resume so that i get accepted easily with Funding..
Please do tell me what all should i do...

Thanks.

National, Internation level technical paper presentations (Maily IEEE pulications) will booost up resume for Masters or PhD admissions in USA. You need to have good GRE score to get into ASU. ASU is offiering less funding for international students. And there are lot many univs which offers scholarships and funding .
