A tip for H4 visa holders - As you are already in the US apply for some assistanships very early during the admission process . The professor may call for a meeting and you might ace it . You never know unless you tried . In my case the prof was a very old man and did most of the talking (phew).No technical questions just about the course work ,academic profile etc .
