预约的时候他说要交，然后我去查了网站，
3.B.5. When is paying a SEVIS I-901 fee not required for continuing students?
Return to the United States to Continue Studies
Continuing students do not have to pay the SEVIS I-901 fee when returning to
United States or applying for a visa to return to the United States after:
* An absence of less than five months to continue the same program of
study
* Completing authorized overseas study as part of the current program (
this absence may exceed five months)
这说的是不交。我同学都没有交过。请问这是怎么回事。。。谢谢
