回复：来美国做exchange student, j1 waiver该怎么写豁免理由？

how come no body respond?

1st paragrapth:
introduce yourself & stating your importance & contribution

2nd paragraph:
explain your research in a more generic way (comon folks can understand, hopefully) Next, saying the length of the research requires me to staying longer so I can contrbute more to the break through of so & so technology.

Good luck.
