Please HELP: Can international students get 100% financial aid in the US?

Tweet

I have searched all over the internet about the different financial aid programs, especially those availble to students outside the US seeking to attend a college or a university. But I did not fully-understand many of them, and thought maybe someone here could clarify that to me, or perhaps an international student has gone through this and now is a student in the US. And also if anyone has experienced the work-study programs to help with the living expenses. Please provide me with any info you know. I'll appreciate any help. Thank you!
